Abstract

A system including a power modulation device and an active voltage balancing system is provided. The power modulation device includes first and second semiconductor switches in series. The active voltage balancing system includes a differential voltage logic configured to detect a voltage difference between the first and second semiconductor switches and edge capture logic configured to detect a time difference between when the first and second semiconductor switches are switched. The active voltage balancing system further includes a micro-controller configured to output first and second gate drive signals to drive the first and second semiconductor switches. The micro-controller is configured to tune the first and second gate drive signals based on the voltage difference to compensate for voltage imbalance and the time difference to compensate for drive signal asymmetry to actively balance a voltage between the first and second semiconductor switches.
