摘　　要：目前的超声波电机驱动电路广泛采用推挽式电路作为DC/AC升压变换器。推挽式变换器的负载通常是由超声波电机与电感构成的LC串联匹配电路。由于工作方式有别于传统的DC/DC应用,且负载特殊,所以超声波电机驱动电路中的推挽式变换器工作过程较为复杂。详细分析了这一工作过程,有助于深入了解超声波电机驱动控制装置的非线性特征,也有助于该装置的合理设计。The push-pull convertor is widely used in ultrasonic motor drive as a DC/AC step-up convertor.In this application,the load of the convertor is the LC series compensation circuit in general.Because the operation mode is different from the traditional DC/DC applications,and the non-linearity of the load,the push-pull convertor used in ultrasonic motor drive is analyzed in detail for its more complex operation.The analysis will help to make right design of the convertor,and also will help to understand the non...
