Abstract :
High voltage chargers are being used in the equipments such as electrical vehicles, uninterruptible power supplies and aircrafts. The converter introduced here is based on bi-directional boost topology. The output voltage of batteries set is larger than the input source voltage amplitude, and this converter can transfer the energy both from the source to the batteries bank and vice versa. Input source voltage is sine wave and the output voltage is DC. Both conversion of AC-to-DC and DC-to-DC is performed in one stage and the control scheme of switches is based on hysteric control method to achieve the unity power factor. One can use the electrical equations presented here to define the converter and EMC filter elements value. Finally, simulation results performed on a typical converter show the control method authenticity and effectiveness of the analyses presented here. Also some suggestion for the future works is proposed.
