Abstract:
A control circuit for an inverter. The control circuit includes a first pulse width modulation (PWM) module configured to produce first and second complementary PWM signals, and a second PWM module configured to produce a third and fourth complementary PWM signals. PWM switching logic is coupled to the first and second PWM modules and is adapted to be coupled to a switch network. The switch network includes first, second, third, and fourth switches coupled in series between a first voltage terminal and a second voltage terminal. The PWM switching logic is configured to produce control signals for each of the first, second, third, and fourth switches in response to the first and second complementary PWM signals and to the third and fourth complementary PWM signals.
