Snubber energy recovery circuit for protecting switching devices from voltage and current |
摘要 |
A snubber energy recovery circuit for protecting switching devices from current and voltage, which comprises a snubber circuit connected in parallel with a switching device, a recovery path for recovery the energy stored in the snubber circuit, and a constant-current source for maintaining current flowing in the recovery path at a constant value. The snubber circuit is composed of a snubber diode and a snubber capacitor, with one end of the recovery path being connected to the junction point of the snubber capacitor and snubber diode.
