Dhandapani, K and Reddy Sathi, R (2011) Embedded controlled low-frequency AC to high-frequency AC converter fed induction heater. Journal of Engineering, Design and Technology, 9(1), pp. 7-18. ISSN 1726-0531
Abstract
Purpose – The purpose of this paper is to present, a novel boost-active clamp bridge single stage high-frequency zero voltage soft-switching-pulse width modulation (ZVS-PWM) inverter, which converts the utility frequency AC power into high-frequency AC power with an embedded controller. This single stage high-frequency inverter is composed of a single-phase diode bridge rectifier, a non-smoothing filter, a boost-active clamp bridge type ZVS-PWM high-frequency inverter, and an induction-heated load with planar type litz wire working coil assembly. Also, the paper discusses how to extend the soft-switching operation ranges and improve power conversion efficiency. Design/methodology/approach – The proposed converter is simulated and it is implemented using embedded controller. Findings – It was found that the single stage high-frequency induction heating (IH) inverter using boosted voltage function can eliminate the DC and low-frequency components of the working coil current and reduce the power dissipation of the circuit components and switching devices. Originality/value – The paper shows that the PWM HF inverter is preferred for IH, since it has reduced switching losses and switching stresses. The paper can be extended to PC-based wireless control, which can be part of a distributed control system in major industrial heating systems.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
