After nearly 10 years of efforts, the voltage and current capacity, performance and product stability of my country\'s thyristors have been greatly improved, and fast thyristors and high-frequency thyristors have also been successfully trial-produced. The research and development scope of SCR-based power supply devices has expanded rapidly, and the product types have increased, involving variable frequency speed regulation, medium frequency induction heating, 400-cycle power supply, large-capacity switching power supply, small and lightweight 400kV high-voltage power supply, EDM power supply, sonar power supply, long-wave communication power supply using time-division circuits and very low-frequency navigation transmitter power supply, solid ultrasonic power supply, stepper motor controller and supersonic induction heating (30KW/40kHz), etc.
