This paper presents an intelligent humane stunner for a multi-channel poultry stunning system with current sharing features. This proposed system consists of an interleaved buck-boost converter for driving the stunning system, a full bridge inverter for generating the stunning voltage, a half bridge inverter for generating dither voltages to expedite the breakdown of skin impedance, and a current...
This paper presents flyback converter combined with single-capacitor turn-off snubber for auto-tuning fan rotational speed system. The proposed system can automatically regulate rotational speed of fan, depending on temperature in the chassis of the equipments. Its control algorithm is to regulate output voltage of the proposed converter. With this approach, the wear and tear of the bearing of fan...
This paper proposes a high step-up voltage ratio of full-bridge converter associated with LLC resonant circuit for sterilizing microbe applications. The proposed circuit structure adopts full-bridge converter to generate a high DC voltage, while the LLC resonant circuit is used to recover the energy trapped in leakage inductance of transformer and to reach zero-voltage switching feature increasing...
This paper proposes an interleaved buck-boost converter with a single-capacitor turn-off snubber to reduce the switching loss at turn-off transition and to limit rising rate of voltages across switches for reducing spike voltage. In addition, the proposed converter adopts coupled inductor to attain a high step-up voltage ratio and operates in an interleaved fashion to reduce output current ripple...
