| PURPOSE:To reduce power consumption at the rise of power supply voltage and to save electric power by operating a rectifier device usually as a full-wave rectifier circuit, and at the rise of the power supply voltage, operating the device as a half-wave rectifier circuit. CONSTITUTION:When the voltage of an AC power supply 1 is a prescribed value or less, a signal is outputted from a control signal output terminal 83 of a decision circuit 8, so that a thyristor 7 is turned on. Thereby, the rectifier device 2 operates as a full-wave rectifier circuit and a DC output is obtained from an output terminal 6. When the voltage of the AC power supply 1 is the prescribed value or more, no signal is outputted from the control signal output terminal 83 of the decision circuit 8, so that the thyristor 7 is turned off. Consequently, the rectifier device 2 operates in the course of a diode 24, a capacitor 3, a resistor 4, and a diode 22 as a half-wave rectifier circuit only when the upper terminal of the AC power supply 1 is positive. Thus, the power consumption of a power transistor 51 is sharply reduced as compared with that of the full-wave rectifier circuit. | ||||||

| PURPOSE:To charge a smoothing capacitor up to a reliable voltage by providing a current limiting means in the input end of a switching means and obtaining the detection voltage of a voltage comparing means from the output of this current limiting means. CONSTITUTION:A power supply device consists of a pulsating current supply means 1, a voltage comparing means 2 which discriminates whether a pulsating current voltage Vin is higher than a set voltage Vref or not, a switching means 3, a control means 4 of this means 3, and a smoothing means 5. When the difference between the pulsating current voltage Vin and an output voltage Vout is large, the switching means 3 is turned on to charge a smoothing capacitor 17, and the output voltage Vout is supplied to a load. In this case, a resistance 21 is inserted as a current limiting means 20 to the input end of the switching means 3. Thus, a voltage drop occurs by the resistance 21 and a charging current (i), and charging is terminated with a pulsating current voltage Vin' which is higher than the output voltage Vout by the forward voltage of a diode 18, and the smoothing capacitor 17 is charged up to a more reliable voltage. | ||||||

| PURPOSE:To make a connection automatically and securely by selecting the 1st TRIAC through a comparator and conducting electrically between 100V taps of a transformer when a plug is connected to a 100V tap, and conducting between 200V taps when the plug is connected to a 200V socket. CONSTITUTION:The transformer 4 has a common tap 6, tap 7 for a 100V group, and tap 8 for a 200V group at the primary coil 5, and further has secondary coils 9 and 10.

| PURPOSE:To foreknow assuredly voltage drop, by comparing the voltage of a battery power supply with the voltage of an automatic voltage controlling circuit and then setting the working voltage of a voltage reduction detector which is contained in a load which works through the automatic voltage controlling circuit on the basis of the detected voltage reduction. CONSTITUTION:A voltage VBB is supplied to an automatic voltage control circuits (AVR) 1 and 2 and a voltage reduction setting circuit 7 from an external power supply VDC or a built-in battery power source VB. The AVR1 delivers the voltage VDD and applies it to the circuit 7 along with a load 1 and the AVR2. A TRQ3 is turned on when the difference between the VBB and VDD is large and then turned off with about 0.6V. At this time point, a TRQ4 is turned on and the value drops suddenly for an equivalent resistance that decides the working voltage of a voltage drop detecting IC connected to a terminal 3a of a load 3. At the same time, the set voltage for detection of the voltage drop rises up suddenly to exceed the VDD. Thus the voltage drop detecting signal is delivered. A microprocessor of a load 4 reads out the set voltage and displays it to the load 3 with the liquid crystal. In such a way, a voltage drop is know previously. Such a power supply is suited to an RAM. | ||||||

| PURPOSE:To simplify the constitution of the titled circuit, by dividing the reference voltage to be compared with a power supply voltage through a comparator into a nonlinear ratio, then performing the subsequent processes in a linearized form. CONSTITUTION:A reference voltage dividing circuit 12 consists of a series connected substance of resistances R11-R14 and R15 and divides the reference voltage Vr to be applied to a reference voltage input terminal 13 to deliver the voltages (1/1.414)Vr, (1/1.732)Vr, (1/2)Vr and (1/2.236)Vr to points C1-C4 respectively. These output voltages are compared with the power supply voltage V0 supplied from a terminal 11 through each unit comparator of a comparing circuit 14. The outputs d1-d4 are set at logic value 1 when the V0 is higher than the output voltage and at logic value 0 when the V0 is lower than the output voltages respectively. Thus the contents of a shift register 15 is decided. Then a voltage supply time width deciding circuit 17 detects the contents of the register 15, and the supply voltage is controlled. | ||||||

| PURPOSE:To exclude a means to obtain the effective value of a non-sinusoidal wave and a load voltage detecting means and accordingly to simplify the constitution of circuit, by carrying out the load phase control through the detection of the power supply voltage without detecting the load voltage. CONSTITUTION:A phase controlling switch means 13 like a triac, etc. is connected between a commercial AC power supply 11 and the load 12; and detecting means 14 and 15 detect the voltage value of the power supply 11. Furthermore a voltage-ignition phase converting means 16 decides the ignition phase of a switching means 13 in accordance with the output of the means 15. And an ignition pulse generating means 18 gives the ignition to the means 13 after generating an ignition pulse P with the ignition phse decided by the means 16. For instance, the means 18 supplies the voltage Vtheta corresponding to an ignition phase angle delivered from the means 16 and a pulse ZCP delivered from a zero cross detecting circuit 17 to produce the pulse P having a phase angle theta to the pulse ZCP. | ||||||

| PURPOSE:To ensure the optional setting for the change of time limit to the fluctuation factor of power supply voltage, by amplifying the fluctuation of the power supply voltage through a simple constitution. CONSTITUTION:When a power supply switch 2 is closed, the reference voltage set at a constant level is applied to the gate terminal of a PUT12. At the same time, a TR17 and a thyristor 16 are turned on and off respectively. Accordingly no current flows to a solenoid 15, and the switch 2 is kept closed with conduction to a heater 14. When the charging voltage of a capacitor 6 reaches the reference level, the PUT12 is turned on with the TR17 turned off. The current flowing to a constant voltage diode 9 flows into the gate of the thyristor 16 to turn on the thyristor 16. Then the current flows to the solenoid 15, and the switch 2 opens to discontinue the conduction to the heater 14. With the fluctuation of the power supply, the charging voltage to be applied to a CR integral network 3 becomes equal to the voltage obtained by dividing the voltage obtained by under-cutting the constant voltage VZ by resistances 19 and 20 and by the function of a constant voltage diode 18. | ||||||

| PURPOSE:To cause a change of time limit more than an inverse proportion, by comparing the voltage obtained by subtracting the fluctuation of the power supply voltage from the constant voltage output of a constant voltage circuit with the charging voltage of a charging capacitor in a CR integral network and then controlling the conduction time of a load. CONSTITUTION:When a power supply switch 2 is closed, a heater 20 conducts to charge a capacitor 6. When the charging voltage of the capacitor 6 reaches the gate voltage of a PUT12, the PUT12 is turned on. Then a pulse output is delivered to a cathode terminal 13. Accordingly a thyristor 19 is turned on to flow the current to a solenoid 18. Thus the switch 2 is opened to cut off the current to the heater 20. In case the power supply voltage has a fluctuation, the voltage proportional to the power supply voltage is subtracted from a certain level of voltage decided by a constant voltage diode 9. As a result, the changing factor of the gate voltage of the PUT12 becomes larger than the fluctuation factor of the power supply voltage. | ||||||
