6.1 SELECTION OF POWER DEVICES IN A THREE-PHASE INVERTER
Previous chapters have explained the operation of a three-phase converter and the need for pulse width modulation (PWM). This chapter investigates the three phase power converter as a system, outlining packaging and protection problems.
Power semiconductor devices for a three-phase power converter should be selected after determining the power converter ratings from the application requirements and taking into account the cooling and stress requirements for a given power level.
When the power converter is used within a motor drive, its rating depends on the motor characteristics as it follows.
