“…A paper published by K. Marn-Go and J. Young-Seok [11] demonstrates a variation of this circuit topology; however as demonstrated in the paper, this is only used on a low power application and has not been tested at high power. Furthermore, voltage sharing across the proposed circuit IGBT is not guaranteed in every instance of operation, thus the circuit needs additional measures to ensure voltage sharing across the IGBT switches.…”

Over the next five years, there will be a substantial increase in the number of all-electric (EVs) and hybrid electric vehicles (HEVs). These vehicles will be utilizing onboard electrochemical energy storage devices (batteries) that require full or part recharging by connection to a low voltage utility network that supples domestic or light industrial users. Therefore a suitable uni-or bi-directional power electronic converter is needed to act as a battery charger and convert the AC supply to DC, or vice versa. This paper discusses the design of a 9kW battery charger that is modular, has a balanced three-phase input, is near unity power factor and has no electrolytic capacitors. Also 3 novel power converter snubber designs for use in a single phase leg of the battery charger are demonstrated. Important factors that dictate the design of such converters are discussed and simulation and practical results are considered.I.

“…A turn's ratio of 0.5 is chosen to minimise the stresses on the switches [2]. This two switch flyback converter has a high efficiency and wide operating range [3]. An easy way to comply with the conference paper formatting requirements is to use this document as a template and simply type your text into it.…”

Performance of power electronic converters has become a major concern in the present day. Converters should be designed with the objective of gaining a high efficiency, increased reliability and less complexity. This paper presents the reliability analysis of three converters. Reliability of two-stage Interleaved boost converter, two-stage and single-stage PFC converter is measured. It is shown that number of components in a device effects the reliability of a system.

This paper proposes an actively clamped two-switch flyback converter. Compared to the conventional two-switch flyback converter, the proposed two-switch flyback converter operates with a wide duty cycle range. By using an active-clamp circuit, the proposed converter achieves zero-voltage switching for all of the power switches. Zero-current switching of an output diode is also achieved. Thus, compared with the conventional converter, the proposed converter realizes a higher efficiency with an extended duty cycle. The performance of the proposed converter is verified by the experimental results with use of a 1.0 kW prototype circuit.
