Nowadays, pulse width modulation (PWM) is a most popular technique for variable frequency inverter. PWM inverter has very good steady-state characteristics, although the switching frequency is limited by the effect of the parasitic elements and by the switching losses. These problems and the demand for higher switching frequency have stimulated much interest in resonant power conversion that reduces the switching loss and provides insensitivity to parasitic elements.To get higher performance on resonant converter, three methods of space vector control based variable structure system for input converter and two control methods for output inverter were studied on the parallel resonant DC link dual converter that had been studied in our laboratory. These studies were carried out by computer simulation. As the result, rhomboid switching control for input converter and filtered output voltage control for output inverter were most suitable methods to deduce the switching losses and low-order harmonics of the output current on the resonant converter.

脉宽调制（PWM）技术是目前应用最广泛的变频技术. PWM逆变器具有非常好的稳态特性，尽管开关频率受到寄生元件的影响和开关损耗的限制。这些问题和对更高开关频率的需求已经刺激了对谐振功率转换的极大兴趣，谐振功率转换降低了开关损耗并且提供了对寄生元件的不敏感性。在已研究过的并联谐振直流环节双变换器的基础上，研究了输入变换器的三种基于空间矢量控制的变结构系统控制方法和输出逆变器的两种控制方法。我们的实验室这些研究是通过计算机模拟进行的。结果表明，菱形开关控制输入变换器和滤波输出电压控制输出逆变器是降低谐振变换器开关损耗和输出电流低次谐波的最佳方法。
