Complementary gate drive signals resulting from PWM process with 0V input signal.

Typical PWM process: tri(t) and mod(t) (top), output bridge voltage (middle), and load current (bottom).

Overmodulation PWM process: tri(t) and mod(t) (top), output bridge voltage (middle), and load current (bottom).
