This paper presents a new synchronous boost converter without input diode bridge. Also its source voltage is clamped using a capacitor. This converter employed as an electric vehicle (EV) charger. Its control circuit designed so that the converter input current is sinusoidal and in-phase with the main voltage, then its power factor (PF) reaches unity. It is able to bi-directional power flow capability. A bias capacitor connected in series with the ac source provides a dc voltage clamp at the input, thus input voltage remains always positive. This converter may be controlled to draw sinusoidal average current at the ac side that is either in-phase or any phase difference from the ac source. Hence, it can provide either unity power factor rectification or inversion. Mosfet devices with anti-parallel diodes are used as switches. The efficiency achieved was over 90% and the THD of the input current is under 3%. High frequency noise filter where is placed in the input side guarantees the electro-magnetic compatibility. This topology is superior to conventional rectifier followed by a dc/dc boost converter because of diode bridge elimination and removal of crossover distortions that are inevitable in conventional Active Power Factor Correction (APFC) circuits. Finally, the proposed converter is simulated using Psim software under the hysteresis control method. Very good agreement between the theatrical and simulation results are obtained.

W artykule opisano przekształtnik typu boost bez wejściowego mostka diodowego. Przekształtnik zastosowano jako układ ładujący w pojazdach elektrycznych. Układ zaprojektowano w ten sposób że sinusoidalny prąd wejściowy jest w fazie z napięciem a więc spółczynnik mocy jest równy jedności. Kondensator na wejściu separuje składową stałą napięcia ładującego.
