专利汇可以提供Transition integration switching amplifier专利检索，专利查询，专利分析的服务。并且A transition integration switching amplifier for controlling the application of a source voltage for driving an inductive load such as a four-pole, capacitor phased, hysteresis synchronous motor. Symmetrical circuits are provided wherein identical signals of opposite phase control the operation of transistor switches for application of the voltage source to a center tapped motor stator. The signals would be applied to a coupling transistor, the output of which controls the input of the transistor switches. A collector to base capacitor forces a controlled transition between the saturated and cut-off states of the transistor and eliminates any high voltage transients across the transistor that may arise due to energy stored in the inductance of the motor stator.，下面是Transition integration switching amplifier专利的具体信息内容。
1. A switching amplifier comprising: transistor means responsive to input operating alternating current signals for selectively connecting and disconnecting an external source potential to an inductive load, and capacitor means coupled to the collector and base electrodes of said transistor means for controlling the rise and fall times in the output signal therefrom to prevent exposure of said transistor means to large voltage and current transients from said inductive load, and diode means coupled to the emitter and base electrodes of said transistor means for shunting large signal transients that may appear across the emitter-base junction of said transistor means due to the collector-base junction being forward biased from an inductive motor load with transformer coupling.
2. The switching amplifier as set forth in claim 1 further including: second transistor means coupled to a source of square wave alternating current signals for generating said operating alternating current signals of predetermined voltage and current characteristics which are coupled to said first mentioned transistor means.
3. The switching amplifier as set forth in claim 2 further including a symmetrical circuit responsive to signals of the opposite phase with respect to said source of square wave alternating current signals, said symmetrical circuit comprising third transistor means responsive to said opposite phase signals for generating operating alternating current signals of predetermined voltage and current characteristics, fourth transistor means coupled to said third transistor means and responsive to said operating alternating current signals for selectively connecting and disconnecting said external source potential to a second inductive load, second capacitor means coupled to the collector and base electrodes of said fourth transistor means for controlling the rise and fall times in the output signal therefrom to prevent exposure of said fourth transistor means to large voltage and current transients from said second inductive load, and second diode means coupled to the emitter and base electrodes of said fourth transistor means for shunting large signal transients that may appear across the emitter-base junction of said fourth transistor means due to the collector-base junction being forward biased from said inductive motor load with transformer coupling.
4. A transition integration switching amplifier for alternately connecting and disconnecting a drive source potential to an external inductive load in response to square wave alternating current input signals, said amplifier comprising: transistor means responsive to said square wave alternating current signals for selectively connecting and disconnecting said drive source potential to said inductive load, capacitor means coupled to the collector and base electrodes of said transistor means for integrating large signal transients generated by the inductance of said inductive load and applying said integrated signal in a negative feedback relationship to the base of said transistor means to thereby eliminate said signal transients, and diode means coupled to the emitter and base electrodes of said transistor means for shunting large signal transients that may appear across said base-emitter junction of said transistor means.
5. The switching amplifier set forth in claim 4 further including a symmetrical circuit responsive to signals of the opposite phase with respect to said square wave alternating current input signals, said symmetrical circuit comprising: second transistor means responsive to said opposite phase signals for selectively connecting and disconnecting said drive source potential to a secOnd inductive load, second capacitor means coupled to the collector and base electrodes of said second transistor means for integrating large signal transients generated by the inductance of said second inductive load and applying said integrated signal in a negative feedback relationship to the base of said second transistor means to thereby eliminate said signal transients, and second diode means coupled to the emitter and base electrodes of said second transistor means for shunting large signal transients that may appear across said base-emitter junction of said second transistor means.
