摘　　要：为了适应新能源发展的需要,将数字型PWM控制方式应用于全桥LLC谐振变换器。该方式不仅可以解决传统变频控制磁性元件设计与优化难的问题,而且还满足了新能源对DC/DC变换器功能的要求。数字型全桥LLC谐振变换器具有功率密度大、效率高、功能种类多等特点,适用于新能源的发展需求。通过实验验证,该方案可行有效。This paper introduces is a response to the development of new energy by applying digital PWM control mode to full bridge LLC resonant converter. This novel method not only enables the design and optimization of variable frequency control magnetic components,which has proved difficult for the conventional method,but it also can fulfill tough and stringent demands on the DC/DC converter imposed by the new energy. Digital full bridge LLC resonant converter characterized by higher power density,higher efficiency,and multi function demonstrates a better adaptation to the development of new energy and a more feasible and effective performance.
