【摘要】 本文首先对一种新的用于电机驱动的谐振极零电压过渡PWM三相逆变器电路的的工作原理及实验验证结果进行了简单的介绍。用对比的方式,分别对文中讨论的软开关逆变器电路和传统硬开关逆变器电路的功率损耗及工作效率进行了详细的数学分析,给出了功率器件及由其构成的逆变器功率损耗的简化数学模型,该模型适合于三相和单相的逆变器电路。最后的实验结果完全验证了文章中的理论分析结果。更多还原

【Abstract】 In this paper, the principles of the operation of a novel resonant pole zero-voltage-transition PWM inverter for motor drive are simply discussed at first. Using comparative analysis, give out the detailed mathematical method of power loss and efficiency of the discussed soft-switching inverter circuits and conventional hard-switching inverter circuits , and give out the power loss simplified modeling of power devices and inverter circuit, and this modeling fit for single-phase and three-phase inverter circuits. At last, the analysis conclusions are verified by some related experiments.更多还原
