The Application of EWB in Power Electronic Circuit Simulation

The combined device model of power electronic circuit switch device is established by using electronic design automatic software EWB. And then,the subcircuit function of EWB is used to encapsulate the model and thyristor trigger circuit being a block respectively. Lastly,the model and trigger control plate are used to carry out the simulation control over Cuk chopper and phase controlled rectifier. The reults indicate that the model method of combined devices is correct,and that EWB software interface is in intuition,convenience and agility to use,particularly with its virtual instrument and perfectly functional settings,being adaptable to the large scale system simulation in power electronic circuit,whereby laying a solid base for the development of power electronic virtual experiments.
