Interleaved Forward Converter with Ripple-free Circuit for Humane Killer Poultry Applications

摘要

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 10kV, killing voltage of 150 V, killing current of 1A and killing time of 6s has been implemented to verify the feasibility of the proposed poultry killer.
