An isolated fully soft-switched flyback converter with low voltage stress
PESC97. Record 28th Annual IEEE Power Electronics Specialists Conference. Formerly Power Conditioning Specialists Conference 1970-71. Power Processing and Electronic Specialists Conference 1972, 2002 An isolated fully soft-switched PWM flyback power converter topology with low switch voltage stress is proposed. The power converter features the use of the leakage inductance of the 'flyback' coupled inductors to achieve zero-voltage switching (ZVS) and/or zero-current switching (ZCS) of all switching devices. The method of implementation is simply to

A Seven-Level Inverter With Self-Balancing and Low-Voltage Stress
IEEE Journal of Emerging and Selected Topics in Power Electronics, 2020Based on the switched-capacitor (SC) principle, a seven-level inverter is proposed, which can synthesize seven levels containing a single dc source. Moreover, it can further generate more levels by a cascaded extension. Meanwhile, the proposed topology does not require any sensor due to the use of SC technology.

A Novel Nonisolated Ultra-High-Voltage-Gain DC–DC Converter With Low Voltage Stress
IEEE Transactions on Industrial Electronics, 2017Regarding the inherent structure of some nonpolluting resources such as fuel cell (FC) stacks and photovoltaic (PV) panels, the output exhibits a low voltage, which cannot be employed in the common conventional utilizations. Accordingly, an interference dc–dc converter is extremely required.

A New Switched Capacitor 7L Inverter With Triple Voltage Gain and Low Voltage Stress
IEEE Transactions on Circuits and Systems II: Express Briefs, 2020In this paper, a new switched capacitor based multilevel inverter topology is proposed. The proposed topology generates seven level (7L) output voltage using a single dc voltage source along with two floating capacitors. The output voltage of the proposed topology is three-times higher than the input voltage (i.e., gain factor of Vin:Vout = 1:3) along ...

Influence of VFD parameters on voltage stresses in low voltage windings
2016 57th International Scientific Conference on Power and Electrical Engineering of Riga Technical University (RTUCON), 2016Currently the frequency control is widely used to provide high level of induction motors efficiency. Studies show that typical for the variable frequency drive (VFD) severe electro-thermal stresses influencing on the windings insulation negatively affect the windings reliability.

New class-E rectifier with low voltage stress
2016 IEEE Asia Pacific Conference on Circuits and Systems (APCCAS), 2016This paper presents a novel circuit topology of the class-E rectifier by introducing the concept of the class-F rectifier into the basic class-E rectifier. In the proposed class-E rectifier, a harmonic component is added to the switching device of the basic class-E rectifier. Therefore, the proposed class-E rectifier possesses the strengths of both the
