Interleaved forward converter with ripple-free circuit for humane killer poultry applications

The paper proposes a novel application for poultry of humane killing. The proposed poultry killer consists of two forward converter and two half-bridge inverters. In each forward converter, a ripple-free circuit is introduced into the one to achieve output current with ripple-free and to generate a high pulse voltage which is used to induce breakdown of poultry skin, feather or scale in feet. With the approach, forward converter with ripple-free circuit can reduce volume and size of output filter and rapid generate the breakdown of poultry skin to speed up poultry killing. Moreover, half-bridge inverter is used to chop dc voltage into pulse voltage at low frequency for sustaining the desired killing current during poultry killing time. Finally, a prototype under maximum skin breakdown voltage of 10 kV, killing voltage of 150 V, killing current of 1 A and killing time of 6 s has been implemented to verify the feasibility of the proposed poultry killer.
