The Design of LLC Resonant Converter Based on DSP2812

LLC resonant converter with the primary switch is easy to realize the full load range ZVS and the sec-ondary diode is easy to realize ZCS.The resonant inductor and transformer can realize the integration of magnetic components easily,as well as the advantages of wide input voltage range,received wide attention.Using pure resistive normalized gain curve parameters to do the resonant network design,adopting high-speed signal processing DSP2812 advanced control strategies to achieve improved system performance.Finally,the battery charger application example shows the performance of LLC resonant converter.
