Abstract :
A novel model for MOSFETs and SITs (static induction transistors) is developed and used to analyze operational characteristics of high-frequency inverters consisting of MOSFET and SIT switching devices. Numerical analyses are carried out using EMPT, (electromagnetic transient analysis program). The gate control circuit and the switching devices are realized by the subprogram TACS of EMTP. The calculated results agree well with the experimental results, showing that as the load resistance becomes lower or the operational frequency becomes higher, the effect of the capacitance of the switching device and the internal inductance of the inverter increases.<>
