Abstract:
An active rectification system includes a three-level active rectifier and a pulse with modulation (PWM) control portion. The three-level active rectifier includes at least three switches, the at least three switches are selectively switchable between an upper state, a center state, and a lower state. The PWM control portion is in communication with the at least three switches, the PWM control portion is configured and disposed to create an upper carrier signal and a lower carrier signal, and the PWM control portion is configured and disposed to selectively switch the at least three switches between the upper state, the center state, and the lower state in response to a phase disposition of the upper carrier signal and the lower carrier signal.
