摘要

提出一种用于无刷直流(BLDC)电机驱动的无桥(BL)输入并联输出串联(IPOS)型功率因数校正(PFC)非隔离Zeta变换器。深入讨论了BL IPOS PFC Zeta变换器的工作模式，并进一步设计了该变换器驱动无刷直流电机。然后利用电压跟随器技术对变换器进行控制，实现输出电压可控，实现无刷直流调速。相应的，统一的功率因数运算实现了更好的电能质量性能。为避免基于电流控制的高频开关技术产生的开关损耗，在无刷直流电机逆变器中采用了基于六步电子换相的开关方案。进一步，利用MATLAB/Simulink对基于BL IPOS PFC Zeta变换器的无刷直流电机在稳态和动态情况下的驱动性能进行了评估，以测试其在家用电器中的适用性。

A Bridge-less IPOS PFC Zeta Converter Fed BLDC Motor Drive for Home Appliances

A bridge-less (BL) input parallel and output series (IPOS) type power factor correction (PFC) non-isolated Zeta converter is proposed for brush-less direct current (BLDC) motor drive. The operating modes of BL IPOS PFC Zeta converter is thoroughly discussed and further the proposed converter is designed to drive BLDC motor. Thereafter, the converter is controlled using voltage follower technique to achieve controllable output voltage for BLDC speed control. Correspondingly, the unity power factor operation accomplished for better power quality performance. The six step electronic commutation based switching scheme is employed for BLDC motor inverter in order to evade switching losses occurs in current control based high frequency switching technique. Further, the BL IPOS PFC Zeta converter based BLDC motor drive performance under steady-state and dynamic situations are evaluated with the help of MATLAB/Simulink to test its suitability for home appliances.
