摘要
A high-density control circuit for an auxiliary resonant commutation pole (ARCP) circuit is internal to the ARCP package and includes a state machine sequencer for providing control and timing signals to achieve high-efficiency, zero-voltage, and fault-tolerant switching converter operation. The phase leg controller receives as inputs a phase enable signal and a pulse width modulation (PWM) signal from a system controller and gate drive feedback signals from main and auxiliary gate drivers. There are four paths the state machine sequencer can take when making a transition from one dc rail to the other, depending on whether the main diode or main switch is conducting and the magnitude and polarity of the inverter pole output current.
