Active Clamp Interleaved Flyback Converter with Single-Capacitor Turn-off Snubber for Stunning Poultry Applications

The paper proposes an active clamp interleaved flyback converter with a single-capacitor turn-off snubber associated with a full-bridge inverter for stunning poultry applications. The proposed converter can use active clamp circuit to recover the energy of transformer and to achieve zero-voltage switching at turn-on transition. In addition, the proposed one adopts a single-capacitor snubber not only to smooth out switch turn-off transient for reducing turn-off loss but to reduce the ringing voltage of diodes in secondary winding of transformer when switch of the proposed one is operated at turn-on transition. Compared with the counterparts of the conventional converter topologies, the proposed converter has the merits of less component counts, higher efficiency, smaller size, and they are easier to implement. Performance measurements from a prototype have verified feasibility of the overall system design. This designed system has contributed a lot of humane slaughter and has attracted much attention.
