摘要：In this paper, we propose design of the boost converter with hybridtransformer ratio for hybrid power source charging station. This converter is addressedas DC step up converter. This converter has high ratio conversion that converter to DCbus 24 Volt to AC system 220Volt. The combination between resonance modes andpulse width modulation (PWM) is used to achieve high voltage ratio conversion. Theadvantage of proposed method is use only single switching device; therefore it is easy tocontrol. Moreover, voltage stress on diode and switching device is relatively low andindependent from input voltage. The experiment result show that the converter is able tooperates in wide range input voltage and has good conversion efficiency up to 90%.Based on the operation and conversion characteristic, the converter can be operated inpower inverter with duty ratio 0.7-0.8 to synchronizing with AC system
