Portable Resonant Test System

Portable Resonant Test SystemIntroduction: SBPC makes the reactor and tester capacitor in resonant by adjusting the frequency of the power source, then get high voltage and large current from measured equipment. Now it is a new method and trend for high voltage test and widely used in China. SBPC uses special SPWM digital wave-generator chip, resolution is 16 bits, the frequency adjustment fineness could be 0.1HZ if the frequency is 20~300HZ; adopts sine asynchronous...
