Design of Stable Voltage Output of Flywheel Energy Storage System by PWM Mode

在分析飞轮储能系统运行原理的基础上,设计了一种脉宽调制控制式闭环稳压电路,即通过改变一个脉宽调制周期内晶体管的导通时间来实现稳压输出。样机试验证明该电路具有很好的稳压性能,能够满足飞轮系统中负载及转速的变化影响。

A closed loop circuit with stabilized output voltage controlled by PWM mode was designed by analysing the operation principle of flywheel energy storage system, the on-time of the giant transistor in a PWM cycle isregulated in order to stabilize the output voltage. The experiment results showed that the circuh possesses good performance with stabilized output voltage and was capable of satisfying the change of load and rotate speed on flywheel energy storage system.
