POWER SUPPLY SYSTEM FOR CONVERTING AN AC VOLTAGE TO A DC VOLTAGE
摘要
<p>The present invention relates to a power supply system for converting an AC voltage to a DC voltage. The system comprises a bridgeless boost converter for converting the AC voltage to an intermediate high voltage DC; a LLC resonant circuit comprising an insulation transformer device, for converting the intermediate high voltage DC into a low voltage high frequency AC; a synchronous rectifier connected to the resonant circuit, for converting the low voltage high frequency AC into the DC voltage.</p>
