    • A high-temperature, regulated power supply uses wide band gap transistors to drive a Royer circuit. Pulses output from the Royer circuit are gated through a pulse width modulator to control the duty cycle of wide band gap transistors that drive an output transformer. The output of the transformer is rectified and filtered to provide the regulated D.C. output voltage. Regulation is accomplished by sampling the output voltage, comparing it to a reference voltage and using the difference between the output voltage and the reference voltage to control the pulse width modulator. High temperature operability is provided by using wide band gap transistors and iron or steel core transformers. This technique also provides a radiation hard assembly.
    • 高温稳压电源采用宽带晶体管驱动罗伊电路。 来自Royer电路的脉冲输出通过脉宽调制器进行门控,以控制驱动输出变压器的宽带隙晶体管的占空比。 变压器的输出被整流和滤波,以提供稳定的直流输出电压。 通过对输出电压进行采样,将其与参考电压进行比较并使用输出电压和参考电压之间的差值来控制脉宽调制器来实现调节。 通过使用宽带隙晶体管和铁芯或钢芯变压器提供高温可操作性。 该技术还提供了辐射硬组件。
