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 New Switched Capacitor 7L Inverter With Triple Voltage Gain and Low Voltage Stress

IEEE Transactions on Circuits and Systems II: Express Briefs, 2020
In 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 ...

Effect of Voltage Stress on Diagnostic Parameters of Low Voltage Cables

Conference Record of the 2008 IEEE International Symposium on Electrical Insulation, 2008
The 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

27.12 MHz large voltage gain resonant converter with low voltage stress

2013 IEEE Energy Conversion Congress and Exposition, 2013
This 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 ...

Study on the Z-Source Inverter with Low Voltage Stress

Applied Mechanics and Materials, 2013
This paper proposed a kind of low voltage stress Z-source inverter topology. In the topology, the inductors of Z-source can be connected alternatively in parallel during the time of shoot-through and in series during the other time. Thus the network can obtain a high boost factor with a small shoot-through duty ratio and can decrease the voltage stress
