Abstract
A method for an auxiliary device of an auxiliary resonant commutated pole inverter (ARCPI) to determine a boosting time of the ARCPI is provided. The auxiliary device includes an auxiliary switch path that uses a resonant inductor with at least one saturable inductor. The method includes: calculating, by a processor of the auxiliary device, a first boosting time in the auxiliary switch path based on a theoretical resonance inductance and a voltage that are applied to the resonant inductor; determining, by the processor, a second boosting time in the auxiliary switch path based on a look-up table; and determining, by the processor, the boosting time in the auxiliary switch path based on the first boosting time and the second boosting time. The method further includes controlling, by the processor, boosting current of the ARCPI based on the boosting time in the auxiliary switch path.
