Induction Heating Technology and Its Applications: Past Developments, Current Technology, and Future Challenges

“…Domestic [2], [44][45][46][47][48][49][50][51][52][53][54][55][56][57][58][59][60][61][62][63]. [33], [50], [62], [64][65][66][67][68][69][70][71][72][73][74][75][76][77][78].…”

“…17 (c), but differ in the inverter topology. Designs for Europe and America are usually specified for output powers up to 4 kW, and the power converter topology usually chose is the series resonant halfbridge inverter [50], [56]. By contrast, appliances for Asiatic countries are usually designed with 2 kW output power and the preferred topology is the ZVS single-switch quasiresonant inverter [58].…”

Power tracking of resonant inverter with soft-switching over full load range for induction heating applications

“…Since the IH load branch is in resonance, the flowing current is resistive current as the resistance alone resists the flowing current in the pure series resonant tank [15]. The analysis of the simple R -L 0 -C r series resonant tank is carried out and the total impedance of the tank is (2) where Q is the loaded quality, and the normalized frequency is u = f s /f r . For ZVS operation, it is defined as u>1.…”

“…The concept of induction heating came into existence when Michael Faraday introduced the electromagnetic induction principle in 1831. IH has many dominant advantages over the other heating techniques which includes faster heating, increased efficiency, consistency improved process quality, and most importantly its cleanliness and safety [2], [5].…”

“…All these modulation and control algorithms have been implemented either using analog [5] or digital techniques. Nowadays, digital signal processors (DSPs) or field-programmable gate arrays (FPGAs) [2] are commonly used for digital implementation.…”
