Low-loss microwave photonic switching for satellite communication

Optics Letters, 2023
For traditional switching architecture, packet switching performs fine granularity data packet forwarding, but its digital signal processing (DSP) has high power consumption (PC). All-optical switching provides rapid exchange of wavelength resources, which has coarse granularity.

Analytical Estimation of Turn on Switching Loss of SiC mosfet and Schottky Diode Pair From Datasheet Parameters

IEEE transactions on power electronics, 2019
Estimation of switching loss at the early stages of design is essential for determination of switching frequency and selection of power devices. Analytical estimation similar to gate charge method results in fastest and easiest computation when compared ...

A zero switching loss matrix converter

Proceedings of IEEE Power Electronics Specialist Conference - PESC '93, 2002
A low loss bidirectional switch set is proposed for a matrix power converter. The proposed switch is able to turn on at zero current and turn off at zero voltage to achieve almost zero loss and soft switching. Hence, a simple hysteretic current control can now be applied directly to a matrix power converter without adding any additional snubber circuit

Low loss soft switching boost converter

2008 13th International Power Electronics and Motion Control Conference, 2008
A new soft switching boost converter is proposed in this paper. The conventional boost converter generates switching losses at turn on and off. Because of those, the whole system efficiency is reduced. The proposed converter utilizes soft switching method using an auxiliary switch and resonant circuit.

Achieving Zero Switching Loss in Silicon Carbide MOSFET

IEEE transactions on power electronics, 2019
Due to the unipolar conduction mechanism, the switching loss of silicon carbide (SiC) metal-oxide-semiconductor field-effect transistor (mosfet) is reduced significantly when compared with silicon insulated gate bipolar transistor (IGBT).

Low-loss self-switching bandstop filter

2016 46th European Microwave Conference (EuMC), 2016
A new switchable low-loss bandstop filter is presented based on an indirect switching method combined with all-pass coupled lines. The proposed design allows switching between an all-pass mode and a bandstop filter mode for On/Off operation of a bandstop response.
