Grounding Protection Capacitors
Special Application

Grounding Protection Capacitors

Capacitors for thyristor commutation protection and system snubber protection in medium and low-frequency induction heating and melting resonant power supplies — limiting overvoltage, suppressing high-frequency oscillation, and safeguarding power semiconductor devices.

Applications

  • Medium/low-frequency induction power thyristor protection
  • System snubber protection
  • Overvoltage suppression
