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...
switching lossesTwo insulated-gate bipolar-transistors (IGBTs) inverter leg modules of identical power rating have been manufactured and tested. One module has silicon-carbide (SiC) Schottky diodes as anti-parallel diodes and the other silicon PiN diodes. The po...

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 ...
As a consequence, there is the need to provide electronic power devices with lesser and lesser both static and dynamic power losses to improve the efficiency thereof at the required frequencies. In this context it may be very important to reduce or remove also the printed circuit board ...
The circuit conduction losses are also minimised, since the resonant capacitor charging current flows only through an inductor and a diode. The main and auxiliary IGBT share a common emitter connection, facilitating direct drive to them. The circuit is suitable for application to active power factor...
