| Abstract |
This paper treats a simple power loss analysis simulator which can actually estimate the total power
losses of three phase voltage source soft-switching inverter as well as hard-switching inverter. To estimate
switching power losses and conduction power losses of switching semiconductor power devices; IGBTs,
incorporated into the inverters and converters, proposed practical simulator is making use of feasible
switching power loss data tables and conduction power loss data tables which are accumulated from the
measured transient switching operation and periodic steady-state conduction voltage and current operating
waveforms of semiconductor switching power devices. The effectiveness of feasible simulation technique
and power loss evaluations for power electronic conversion circuits and systems has been confirmed on
the basis of simulation and experimental results under the conditions of soft switching and hard switching
sinusoidal PWM schemes. |
