摘要
Abstract
In wide output voltage and load current range applications such as standard communication rectifier and electric vehicle charging module,etc.,since the non-monotonic phenomenon in high frequency region of the LLC resonant converter and limiting considering of the too high switching frequency,a simple frequency control is difficult to satisfy need,the usual approach is to introduce PWM control on the basis of PFM. Currently,the research about the monotonicity of LLC resonant converter in PWM control mode is rare. By simulation and experiment,the monotonicity of LLC resonant converter in PWM control and the nature of the non-monotonic behavior under particular duty cycle were researched,the range of non-monotonic duty cycle was tested. At last,the practical solution was introduced according to the experiment results.关键词
