Abstract:
An input power conditioning circuit (PCC) for a switched-mode power converter includes a hybrid full wave rectifier. Hybrid rectification is provided by a main rectifier and a matched virtual junction (VJ) rectifier, both with four-transistor gate fully cross-coupled. The VJ rectifier includes a voltage divider (such as a resistive voltage divider) to generate a virtual junction reference voltage VJ_ref (which can be less than transistor Vth). A power conversion controller (such as a boost controller) includes circuitry (such as an error amplifier) to regulate the input voltage VIN (main rectifier) to be substantially equal to VJ_ref from the VJ rectifier. Hybrid rectification, with VIN regulation, can be used to eliminate reverse (flow back) current, improving power conversion efficiency.
