Abstract:
The present disclosure provides a method, control circuit, and non-transitory computer-readable medium for adjusting a boosting current of an auxiliary resonant commutated pole inverter (ARCPI). The method includes: (1) providing an input to trigger a first counter; (2) triggering a second counter based on determining that the first counter reaches a boosting time of the ARCPI; (3) stopping the second counter based on determining that a detection signal is received, and obtaining a time interval counted by the second counter; and (4) adjusting the boosting current based on determining that the time interval is equal to a sum of a first time and a blanking time.
