Active clamp interleaved forward converter with single-capacitor turn-off snubber for stunning poultry applications

This paper proposes an active clamp interleaved forward converter with a single-capacitor turn-off snubber constructed with a full-bridge inverter for stunning poultry applications. The proposed converter can use active clamp circuit to recover the energy trapped in magnetizing and leakage inductors 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 voltage at turn-off transition for reducing switching loss but to decrease the ringing voltage across output freewheeling diodes of the proposed converter at turn-on transition of each switch. As 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.
