WebJul 15, 2024 · Soft-switching converters can exhibit reduced switching loss, at the expense of increased conduction loss. Obtaining zero-voltage or zero-current switching requires that the resonant elements have large ripple; often, these elements are operated in a manner similar to the discontinuous conduction modes of the series or parallel … WebAug 9, 2024 · IEEE Transactions on Industrial Electronics Circuit-level analytical models for hard-switching, soft-switching, and $dv/ dt$-induced false turn on of SiC MOSFETs and their experimental validation are described.
WebOct 14, 2024 · 2.1 Proposed soft switching topology and modulation method. The proposed soft-switching topology of a single-phase ANPC inverter is shown in Fig. 1.The DC source of the inverter is V DC, which is a constant in this paper.The supporting capacitors are C DC, which are often identical and more than 1 mF in practical designs. … WebWith hard switching, collector current and collector-emitter voltage change sharply, causing switching noise and loss. Hard switching is used for simple switch, motor drive inverter, and switched-mode power supply applications. In contrast, soft switching uses an LC resonant circuit to turn on and off a device at zero current or voltage.
WebAug 5, 2014 · During soft switching the voltage falls to zero (rather than just a minimum) before the MOSFET is turned on or off, eliminating any overlap between voltage and current and minimizing losses. (The technique can also be used to switch the MOSFET when current, rather than voltage, reaches zero. This is known as Zero Current Switching …
