Suitable for the Design of Electric Vehicle Charger LLC Half-Bridge Converter

The development of new energy vehicles is the only way for China to move from a large automobile country to an automobile power, and it is a strategic measure to address climate change and promote green development. Based on the electric vehicle charger, the design of the half-bridge LLC resonant circuit changer is carried out to improve the charging device of new energy electric vehicles, and the resonant parameter design and resonant frequency gain system design of the half-bridge LLC half-bridge converter of the electric vehicle charger LLC are studied by analyzing the working principle and working characteristics of the half-bridge LLC resonant circuit. Through MATLAB for half-bridge LLC resonant circuit and debugging, observe the waveform and data to obtain the simulation model can effectively ensure the stability of the output, in the full load and heavy load output voltage fluctuation is within the range of change, thus verifying the feasibility of the design of the electric vehicle charger LLC half-bridge resonant converter, therefore, the LLC resonant converter can improve the conversion efficiency of the DC-DC converter, so that the charging efficiency is greatly accelerated, so as to achieve fast charging. It is efficient and fast to apply to the needs of high-power power supplies, thereby promoting the development of new energy vehicles.
