三相AC-AC直接频率变换器拓扑结构及其控制方法
Abstract:
本发明提供的是一种三相AC-AC直接频率变换器及其控制方法。三相AC-AC直接频率变换器包括三相电源、滤波器、主电路和缓冲电路，其特征是：电源接滤波电路再接主电路，主电路接缓冲电路。三相AC-AC直接频率变换器的控制方法是：第一种控制方法是采用SPWM控制方式，第二种控制方式是滞环电流控制。本发明拓扑结构简单，控制方法简单易行功率变换级数少、可靠性高。
Abstract(English):

The invention provides a three-phase alternating current-alternating current (AC-AC) direct frequency converter and a control method thereof. The three-phase AC-AC direct frequency converter comprises a three-phase power supply, a filter, a main circuit and a buffer circuit, and is characterized in that the power supply is sequentially connected with the filter and the main circuit, and the main circuit is connected with the buffer circuit. The control method for the three-phase AC-AC direct frequency converter comprises a sinusoidal pulse width modulation (SPWM) control mode and a hysteresis current control mode. The converter is simple in topology structure; and the control method is simple, practical and high in reliability, and comprises a few power conversion stages.
