Auxiliary Resonant Commutated Pole Inverter (ARCPI) Operation Using online voltage measurements

This paper demonstrates the operation and control of an auxiliary resonant commutated pole (ARCP) inverter based on online measurement of the collector-emitter and gate-emitter-voltage. This technique is particularly beneficial for inverters with high switching frequency and small resonant tanks where nonlinear effects cannot be neglected. The proposed method has been successfully tested on a prototype converter and provides improved efficiency and stable operation over a wide range of output currents, DC link voltages and chip temperatures.
