H桥电路的一个典型用途是在电源应用中将DC转换为AC。H桥的两个并联支路和两个开关的控制策略决定了它的使用方式。H桥的输入是直流电压源,输出也是直流电压,但其幅度和极性可以控制。 该转换器可以用于通过在保持S3和S4断开的同时闭合开关S1和S2,然后在闭合S3和的同时断开S1和S2来产生方波输出电压。如果这些开关对的...
An H-bridge circuit includes a lower-arm field-effect transistor and a current supplying element that turns on when the drain of the lower-arm field-effect transistor is negatively biased due to regenerative current. When turned on, the current supplying element conducts current from the source ...

在H桥中与互补的PWM一起工作时,一个主要考虑因素是短路可能的可能性,也称为“射击”。 如图5所示,如果同时打开同一腿的两个开关,则H-Bridge配置会产生直接短与接地之间的直接短路。 如果同时打开同一腿上的两个开关,可能会发生射击图5。如果同时打开同一腿的两个开关,可能会发生射门这种情况可能非常危险,因为它可...
motor to the appropriate voltage rail, and it will start to rotate. But this is not the perfect way to drive the motor, especially when other components are involved in the circuit. Here, we will discuss one of the most common and effective methods to drive DC motor - H-bridge circuit....
2.1 电源电路(Power Circuit) 如图2所示,电源电路由Vdc=24 V的直流电源电压供电。H桥由两个IGBT半桥功率模块组件组成,为感性负载供电。脉宽调制(PWM)开关信号从PLECS RT Box库的PWM捕捉块获得。功率模块组件的建模和子循环平均处理在[1]的工作中进行了描述。直流输入电压和输出电感电流的测量值通过PLECS RT Box库中...
