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.

Effect of Voltage Stress on Diagnostic Parameters of Low Voltage Cables
Conference Record of the 2008 IEEE International Symposium on Electrical Insulation, 2008The most important property of the insulation is the dielectric strength, because the main function of the insulation is isolating of the electrodes on different potential. Due to the stresses the dielectric strength is decreasing till it reaches the limit of safety operation. Aging tests are performed on insulations to predict the expected lifetime of

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

A High-Voltage ZVZCS DC--DC Converter With Low Voltage Stress
IEEE Transactions on Power Electronics, 2008A high-voltage zero-voltage-zero-current-switched dc--dc converter with low voltage stress is presented in this paper. Its circuit structure is extended from a previously developed zero-voltage-switched dc--dc converter consisting of six series-connected switching devices, one three-phase transformer, and an output current tripler.

27.12 MHz large voltage gain resonant converter with low voltage stress
2013 IEEE Energy Conversion Congress and Exposition, 2013This paper presents the design and implementation of a high frequency switching power converter with a large voltage gain and air core inductors. Specifically, we demonstrate a 40 W, 30 V to 300 V dc-dc converter switching at 27.12 MHz. Operating at this frequency reduces bulk energy storage over conventional low frequency designs and allows for fast ...
