Abstract
According to some embodiments, a power converter is disclosed. The power converter includes an input electromagnetic interference filter to receive raw AC power and to output filtered AC power. A type-pi filter, and switch, receives the filtered AC power, further filters the received filtered AC power, and receives an indication from a digital controller module that an amplitude, frequency, and phase information of the filtered AC voltage is within a range of acceptable values and outputs the further filtered AC Power. The power conversion circuit receives a signal from the digital controller, receives the further filtered AC power from the type-pi filter and switch, converts the further filtered AC power to a desired voltage and outputs converted AC power. An output electromagnetic interference filter receives the converted AC power from the output electromagnetic interference filter and outputs the filtered converted AC power.
