Patent attributes
A driving device includes a driving primary circuit, an isolating transforming circuit, and at least one driving secondary circuit. The isolating transforming circuit is coupled to the driving primary circuit. The at least one driving secondary circuit is coupled to the isolating transforming circuit. The driving primary circuit receives a control signal and a power signal. The driving primary circuit generates a driving pulse signal according to the control signal and generates a power pulse signal according to the power signal. The driving primary circuit transmits the driving pulse signal and the power pulse signal to the at least one driving secondary circuit through the isolating transforming circuit. The at least one driving secondary circuit receives the driving pulse signal so as to generate a driving signal, and the at least one driving secondary circuit drives a power semiconductor switch unit according to the driving signal.
