摘要 提出一种具有微升压能力的有源功率解耦电路及无电解电容驱动系统控制策略。在同等升压条件下,该电路功率器件驱动信号范围更为合理,在降低逆变器功率器件电压应力的同时,有效地提高了无电解电容驱动系统输入侧电流质量。将直流母线电压交流分量总谐波引入到驱动系统输入参考电流控制中,控制直流母线电压在设定范围内,并实现静、动态工况下无电解电容驱动系统高性能运行。分析该有源功率解耦电路的工作机理,对其数学模型进行推导,详述电路关键参数设计思路。最后,通过原理样机验证该解耦电路及对应无电解电容驱动系统的有效性。

Abstract:A novel active power decoupling circuit with tiny Boost capability and a novel control strategy for the electrolytic capacitor-less drive system are proposed. Under the same boost voltage condition, the working range of power device of the circuit is more reasonable, and the current quality on the input side of the electrolytic capacitor-less driving system is effectively improved while reducing the voltage stress of the inverter power device. The total harmonics of the DC bus voltage AC component are introduced into the input reference current control of the drive system to control the DC bus voltage within the given range, and achieve high performance operation of the electrolytic capacitor-less drive system under static and dynamic conditions. The working mechanism of the new active power decoupling circuit is analyzed, and its mathematical model is deduced. The design of key parameters of the circuit is described in detail. Finally, the effectiveness of the decoupling circuit and the corresponding electrolytic capacitor-less driving system is verified by a prototype.
