Voltage control circuit
专利汇可以提供Voltage control circuit专利检索，专利查询，专利分析的服务。并且PURPOSE: To accelerate the control of a voltage applied on a load by amplifying a control input voltage at an amplifier circuit after setting equal to a feedback voltage from the load and compensating delay in the change of the feedback voltage by estimating the estimated value of the voltage applied on the load corresponding to a control input voltage and the feedback voltage from the load.
CONSTITUTION: The control input voltage is amplified by the amplifier circuit 12 of a voltage control circuit, and the amplification factor of the output voltage is set so as to be almost equal to that of the feedback voltage from a halogen lamp 4. Also, an edge detection circuit 13 as a selection circuit detects 13 the edge of the control input voltage when it changes in step manner, and outputs a pulse corresponding to change width, and the waveform arrangement of the pulse from the circuit 13 is performed by a delay circuit/waveform arranging circuit 14 after being delayed for appropriate time, and it is supplied to the gate of an analog switch 15. Then, the delay in the change of the feedback voltage is compensated, and the control of the voltage applied on the load can be accelerated.
