An electronic circuit is for optimizing or reducing switching losses in current-driven power devices and includes a switching power device connected to an electric load. The power devices has at least one contro
Soft switching consists of eliminating all switching losses by cancellation of the instantaneous power devices at the exact moment of turn-on or turn-off. The losses pK in a switch K take the form: pK=υk.iK where υK and iK are the voltage and the current at the component terminals. ...
(c) Switching speed of semiconductor devices (dvDSdt or dvCEdt). The switching time (tr and tf for rise and fall times, respectively), which are specific to each semiconductor device, determines the dvdt of the phase voltages (Fig. 8(c)). This speed affects power losses, among other iss...
Power devices, components that supply and manage power, are essential to reduce power consumption in all kinds of electronic equipment and to achieve a carbon neutral society. In the global trend to decarbonization and energy saving, IEGTs are used in a wide range of applications, such as high...

Power Losses In A Buck Converter DC Conduction Losses With ideal components (zero voltage drop in the ON state and zero switching loss), an ideal buck converter is 100% efficient. In reality, power dissipation is always associated with every power component. There are two types of losses in ...
GaN-based switching power transistors can operate at high voltages with higher performance and lower losses than previously used silicon (Si) transistors. GaN can operate under high frequency conditions and maintain high performance and efficiency. GaN devices use a GaN-on-Si process that is suitable...
2.Switching losses is prime factor limiting utilization of much higher switching frequency in PWM converter, so soft-switching technology has become the way forward for the telecommunication power supply.因此,软开关技术的应用成为通信电源的发展方向。 3.The dissertation takes the PMSM (Permanent Magnet ...
rapidly. This behavior is attributed to the Finally, the energy losses during the turn-on and turn-off phases for the three devices are calculated using Eqs. (4) and (5). The energy losses of the three devices are shown in Fig. 11. The total switching energy loss of the FG-...
As the turn-on/off is accompanied by transient losses, this type of converter is called a hard-switching circuit. The buck converter is one of three basic structures. The other two are the boost (Fig. 4a) and the buck–boost (Fig. 4b). Each basic structure contains an inductor, a ...
