SOFT-SWITCHING PWM CONVERTER TECHNOLOGIES
Journal of Circuits, Systems and Computers, 1995The switched-mode power conversion technologies have evolved from the basic PWM converters to resonant converters, quasi-resonant converters, multi-resonant converters, and most recently, to soft-switching PWM converters. In this paper, several typical resonant techniques and several soft-switching PWM techniques are reviewed, and their merits and ...

Design of Soft-Switched Inverter
Applied Mechanics and Materials, 2014In order to decrease the exhaust of the switch of inverter bridge arm, the auxiliary resonant net was imbed in the circuit structure which lead to cost ascension and credibility descend. This text discusses to design a DC/AC converter based on simplex single voltage source high frequency chain inversion technology, the output is 0.9KW/115V/400Hz.The ...

Soft switching of KY converter
2008 Twenty-Third Annual IEEE Applied Power Electronics Conference and Exposition, 2008In this paper, the soft switching technique is applied to the KY converter to upgrade the efficiency in the neighborhood of the rated load and hence enhance its capability in industrial applications. The details of the soft switching for the KY converter are illustrated along with some simulation and experimental results to verify the effectiveness of ...

New soft switched PWM converter
PESC Record. 27th Annual IEEE Power Electronics Specialists Conference, 2002A new soft switched pulse width modulation (PWM) converter which operates a fixed frequency is proposed. The main switches are always switched at zero voltage, and the auxiliary switches are softly switched. The voltage and current stresses of the switches are minimized as in conventional PWM converters.

Faster switching for soft magnets
Science, 2018Magnetic Materials The most familiar magnets are permanent magnets like the ones on a refrigerator door. However, for applications in transformers and motors, soft magnets that can rapidly switch their magnetization in response to a magnetic field are used.
