摘　　要：介绍了一种由同步电机和全波升压式C dump变换器构成的新型无刷直流发电机的工作原理 ,详细分析了发电机的PWM调压模式及其对电压脉动的影响 ,在此基础上提出了可改善输出电压脉动的PWM控制方案。A new brushless DC generator is introduced in this paper, which is composed of the full wave boost C dump converter and synchronous machine. The operation principle and PWM control strategies for the generator are analyzed. The influences of PWM control strategies on the voltage fluctuation are investigated. Some measures are presented to decrease the voltage fluctuation of the generator system, and simulation and experiments have been given to show their effectiveness of the PWM strategies.
