Automatic boosting current adjustment for zero voltage switching in auxiliary resonant commutated pole inverter

A control circuit for adjusting a boosting current of an auxiliary resonant commutated pole inverter (ARCPI), comprising one or more processors configured to:

• (1) provide an input to trigger a first counter;
• (2) trigger a second counter based on determining that the first counter reaches a boosting time of the ARCPI;
• (3) stop the second counter based on determining that a detection signal is received, and obtaining a time interval counted by the second counter;
• and
• (4) adjust the boosting current based on determining that the time interval is equal to a sum of a first time and a blanking time.

A non-transitory computer-readable medium, having computer-executable instructions stored thereon, the computer-executable instructions, when executed by one or more processors of a control circuit for adjusting a boosting current of an auxiliary device of an auxiliary resonant commutated pole inverter (ARCPI), cause the control circuit to facilitate:

• (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
• adjusting the boosting current based on determining that the time interval is equal to a sum of a first time and a blanking time.
