5.6 Conduction losses for the IGBT According to Fig. 5.25, during the transients some power is lost. The switching losses are not the only losses of a semiconductor switch. After transient is passed and the device reaches its steady state, some power are lost in form of heat, since the ju...

This unique lateral charge compensation approach is demonstrated to be highly effective in lowering the on-state losses. The experimental results show a 20% reduction in the on-state losses for a 1.7kV device. 展开 关键词: technology trade-off Insulated Gate Bipolar Transistor (IGBT superjunction...
IGBT switching losses reductions during quasi-ZVS turn-off in the PR-SAB are also discussed. With the analysed conduction and switching losses, the improved efficiencies of the PR-SAB over the SAB are analytically determined. As compared to the SAB, the PR-SAB also exhibits up to 20% lower...
It is shown that operating a bridge-type PWM switch mode power converter with asymmetrical duty ratios can eliminate switching losses with no increase in conduction loss. This circuit topology combines the best features of resonant (zero switching loss) and switch mode (low conduction loss) circuits...

In contrast to popular IGBT converters, a negative switch current is capable of flowing through the reverse conducting transistor, which results in different distribution of power losses among the devices. Thus, equations describing the conduction power losses of the transistor and diode are improved ...
IGBTs exhibit a constant current characteristic at much lower voltages than MOSFETs do, so they normally saturate at a low voltage (even the 4kV devices drop hardly 5V), whereas MOSFETs might drop 50V in normal operation (but >100V in fault, so it's not hard to tell or anything). At...
