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.

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 Interleaved Structure with High Voltage-Gain and Low Voltage-Stress on Semiconductors
2019 10th International Power Electronics, Drive Systems and Technologies Conference (PEDSTC), 2019In this paper a high voltage-gain interleaved structure for DC-DC converters is proposed. This structure provides high voltage-gain with reasonable number of elements and low voltage-stress range. Also continuous input current and low current ripple are other advantages of this structure.

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 ...

Study on the Z-Source Inverter with Low Voltage Stress
Applied Mechanics and Materials, 2013This 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

High-Voltage Gain Half-Bridge Z-Source Inverter With Low-Voltage Stress on Capacitors
IEEE Transactions on Industrial Electronics, 2017In this paper, a new topology for half-bridge Z-source inverter is proposed. The proposed topology has only one impedance network. Unlike to the conventional half-bridge inverter, the proposed topology can provide zero voltage level at the output. It also increases output voltage level and stabilizes it in the desired value. Capacitor voltage stress in

A 1-MHz-Modified SEPIC With ZVS Characteristic and Low-Voltage Stress
IEEE Transactions on Industrial Electronics, 2019A 1-MHz-modified single-ended primary-inductor converter (SEPIC) circuit is presented in this paper as an LED driver for automotive headlights. On the basis of traditional SEPIC, only a diode and two capacitors are added; therefore, the circuit structure is relatively simple and the volume is relatively small.
