Experimental design boost ratio converter with hybrid transformer for hybrid power source charging station

In this paper, we propose design of the boost converter with hybrid transformer ratio for hybrid power source charging station. This converter is addressed to voltage controller and maximum power point tracker (MPPT) of photovoltaic (PV) system. In order to get high voltage boost ratio, this converter utilizes a hybrid operation mode, which is a combination of a pulse width modulation (PWM) and resonant modes. This converter requires only a single switch so much easier in the controlling. Voltage stress on the switch and the diode is relatively low and is not affected by changes in the input voltage when the output voltage is kept in constant value. The experiment results show that the proposed converter can work on a wide range input voltage and has a high efficiency at all load levels is equal to ± 78% So this converter can be applied into an alternative energy sources that produce low voltage DC such as photovoltaic system in charging station.
