Zero current switching Type Class DE rectifier

IECON 2012 - 38th Annual Conference on IEEE Industrial Electronics Society, 2012
This paper introduces a zero current switching (ZCS) type Class DE rectifier, along with design procedure, simulation and experimental results. The feature of ZCS type Class DE rectifier is that the diodes maintain ZCS and zero current derivative switching (ZCDS), therefore, switching losses and switching noise are reduced.

A family of zero-current-switching (ZCS) PWM converters using a new zero-current switching auxiliary circuit

The Fifth International Conference on Power Electronics and Drive Systems, 2003. PEDS 2003., 2004
A new family of zero-current-switching (ZCS) pulsewidth-modulated (PWM) converters which uses a new ZCS PWM switch cell is presented in this paper. The main switch and auxiliary switch operate at zero-current-switching turn on and turn off, and the all passive semiconductor devices in the ZCS-PWM converter operate at zero-voltage-switching (ZVS) turn ...

Novel zero-current-switching-zero-voltage-switching converters

PESC Record. 27th Annual IEEE Power Electronics Specialists Conference, 2002
A new family of zero-current-switching-zero-voltage-switching (ZCSZVS) pulse-width-modulation (PWM) converters are proposed. With the proposed ZCSZVS concept, the PSPICE simulation results of the application to a single-switch three-phase PFC rectifier have been obtained and compared with those of hard-switching and ZCT applications in order to show ...

A new zero-current-switching bridgeless PFC

2010 1st Power Electronic & Drive Systems & Technologies Conference (PEDSTC), 2010
This paper presents a new ZCS single phase bridgeless PFC which uses an auxiliary circuit for achieving zero current switching conditions for all switches of conventional bridgeless PFC. The input current is controlled by a peak current controller and output voltage is controlled with a limited band pi controller.

An improved HERIC inverter with zero-current-switching

2017 IEEE Electrical Power and Energy Conference (EPEC), 2017
In this paper, an improved HERIC inverter is proposed. It makes most switching devices operate at zero-current-switching state, by only adding auxiliary inductors on the freewheeling branch. Meanwhile, the dead-time is not required and the modulation of the system is simplified.

Zero Current Synchronization of Opening Switch Contacts

IEEE Transactions on Components, Hybrids, and Manufacturing Technology, 1986
Thermostatic controls switching ac loads at 220 V, 50 Hz consist of a slowly moving thermally activated prime mover operating randomly on a small snap-action switch. An experimental study on the opening characteristic of the snap-action switch has shown that the point on the current wave at which contact separation occurs becomes nonrandom on its ...

Zero-current-switching multilevel modular switched-capacitor dc-dc converter

2009 IEEE Energy Conversion Congress and Exposition, 2009
This paper presents a quasi-resonant technique for multilevel modular switched-capacitor circuit (MMSCC) to achieve zero-current-switching (ZCS) without increasing cost and sacrificing reliability. This zero-current-switching multilevel modular switched-capacitor circuit (ZCS-MMSCC) employs the stray inductance existing in the circuit as the resonant ...

Zero-Current Switching Impedance-Source DC-DC Converter

IECON 2019 - 45th Annual Conference of the IEEE Industrial Electronics Society, 2019
This paper presents a novel soft-switching technique for the galvanically isolated impedance-source full-bridge DC-DC converters. It allows reducing the turn off losses of the inverter switches, which otherwise represent a significant portion of the total power loss in such converters.
