  • Common zero volt reference AC / DC power supply with positive and negative rectification and method of operation thereof
    Patent number: 9608538
    Abstract: A common zero volt reference AC/DC power supply with positive and negative rectification, and method of operation thereof. The power supply comprises an input for receiving an AC input voltage and an output for outputting a DC output voltage, the AC input and DC output having a common zero volt reference. The power supply comprises a first rectifier and a second rectifier, for respectively performing a half-wave rectification of a positive half cycle and negative half cycle of the AC input voltage. The power supply comprises control logic for detecting the negative half cycle of the AC input voltage and activating the second rectifier upon the detection. The power supply comprises a power converter for converting a DC rectified voltage received from at least one of the first and second rectifiers into the DC output voltage.
