A novel switch-mode voltage-doubler rectifier for single-phase supply is presented. It consists of diode bridge circuit and pump circuit with symmetrical arrangement of capacitors. The capacitors with energy storage/transfer capability are charged and discharged by employing the active power semiconductor devices. The rectifier can be operated in the switch mode for pumping action to pump twice the peak supply voltage into the output capacitor and for forcing the input current to follow its sinusoidal reference independent of the working conditions. The prototype tested, using two dual-IGBT power modules, has been implemented to investigate the operation with a PI controller for output voltage regulation. Experimental and simulated results are provided to verify the expected performance in both steady-state and transient conditions.
