A novel technology for high voltage DC SSR is proposed, which can make low voltage signal energy cumulate in short time, and convert it to turn IGBT module on or off with discharge quickly. Feature of the technology is that makes the SSR control directly with the low voltage isolated signal without other biased voltage source. Basic circuit construction and the design method are presented, too. The circuit is analyzed theoretically, simulated with computer, and verified Experimental testing results indicate that the technology is feasible with better performance.
