Abstract
Systems and methods for providing self-driven active AC rectification are provided. In particular, a power conversion system for providing self-driven active AC rectification can be provided. The system can include an input for receiving AC power, a first capacitor and a second capacitor electrically connected in series. The first and second capacitors can also be electrically connected in parallel with a rectifier's load. The system can include a low-side switching element and a shunt resistor electrically connected between the rectifier's load and a system ground. The power conversion system can also include a low-side feedback control loop configured to obtain a low-side feedback signal based on a voltage across the shunt resistor and the low-side feedback control loop can be further configured to control the low-side switching element based, at least in part, on the low-side feedback signal.
