Traditional CLLLC resonant converters do not effectively utilize the switching tubes of the rectifier circuit during operation, resulting in current flowing only through their anti-parallel diodes, leading to high losses and low efficiency. The traditional synchronous rectification scheme based on drain-source voltage is susceptible to the influence of parasitic inductance of switching tubes at high frequencies, which affects the efficiency of synchronous rectification. A detailed analysis of the impact of parasitic parameters on the duty cycle and efficiency of synchronous rectification in CLLLC resonant converters is provided, and an optimization strategy for synchronous rectification based on drain-source voltage is proposed. In a CLLLC resonant converter, the strategy adjusts the turn-off threshold voltage of secondary MOSFET, and improves the efficiency of synchronous rectification by compensating the duty cycle loss time of the synchronous rectifier switching tubes. The experimental results show that the synchronous rectification optimization strategy proposed can effectively reduce the duty cycle loss caused by parasitic parameters and lower the overall losses of CLLLC resonant converter, compared with the traditional synchronous rectification strategy based on drain-source voltage.

传统的CLLLC谐振变换器工作时并未有效利用整流电路的开关管,使得电流仅流过其反并联二极管,损耗大、效率低;而传统的基于漏源电压同步整流方案在高频下易受开关管寄生电感的影响,影响同步整流效率。为此详细分析了寄生参数对CLLLC谐振变换器同步整流占空比和同步整流效率的影响规律,提出一种基于漏源电压的同步整流控制优化策略。该策略在CLLLC谐振变换器中调节其二次侧MOSFET的关断阈值电压,通过补偿同步整流开关管的占空比损失时间提高同步整流的效率。实验结果表明,与传统基于漏源电压的同步整流策略相比,所提同步整流控制优化策略能有效减少因寄生参数造成的占空比损失,降低CLLLC谐振变换器整体损耗。

传统的CLLLC谐振变换器工作时并未有效利用整流电路的开关管,使得电流仅流过其反并联二极管,损耗大、效率低;而传统的基于漏源电压同步整流方案在高频下易受开关管寄生电感的影响,影响同步整流效率。为此详细分析了寄生参数对CLLLC谐振变换器同步整流占空比和同步整流效率的影响规律,提出一种基于漏源电压的同步整流控制优化策略。该策略在CLLLC谐振变换器中调节其二次侧MOSFET的关断阈值电压,通过补偿同步整流开关管的占空比损失时间提高同步整流的效率。实验结果表明,与传统基于漏源电压的同步整流策略相比,所提同步整流控制优化策略能有效减少因寄生参数造成的占空比损失,降低CLLLC谐振变换器整体损耗。

Traditional CLLLC resonant converters do not effectively utilize the switching tubes of the rectifier circuit during operation, resulting in current flowing only through their anti-parallel diodes, leading to high losses and low efficiency. The traditional synchronous rectification scheme based on drain-source voltage is susceptible to the influence of parasitic inductance of switching tubes at high frequencies, which affects the efficiency of synchronous rectification. A detailed analysis of the impact of parasitic parameters on the duty cycle and efficiency of synchronous rectification in CLLLC resonant converters is provided, and an optimization strategy for synchronous rectification based on drain-source voltage is proposed. In a CLLLC resonant converter, the strategy adjusts the turn-off threshold voltage of secondary MOSFET, and improves the efficiency of synchronous rectification by compensating the duty cycle loss time of the synchronous rectifier switching tubes. The experimental results show that the synchronous rectification optimization strategy proposed can effectively reduce the duty cycle loss caused by parasitic parameters and lower the overall losses of CLLLC resonant converter, compared with the traditional synchronous rectification strategy based on drain-source voltage.
