Self oscillated resonant inverters have the advantages of low cost and simplicity. DC-AC power conversion can be achieved without using special drivers. In this study, self oscillated half bridge series resonant inverter topology is designed and applied to induction heater as a boiler part of home type absorption cooler system. The designed system has rapid and stable heating/cooling response compared to conventional resistance heated system. Self oscillated resonant inverter can achieve soft switching and maintain resonant tracking with simple and cheap drive circuit during all heating period.Index Terms-Self oscillated inverter, induction heater, half bridge, zero voltage switching, absorption cooler.

“…Similar studies were focused on the electrical structure of the system and the preference for water as the working fluid [26,27]. Although there are a limited number of papers that discuss gas heating [16,17] or superheated steam generation [7], the researches which examined the energy distribution of the induction air heating system were deemed to be insufficient. With the introduced system, several issues were planned to be solved by utilizing induction air heaters instead of the conventional resistant heaters or fuel fired heaters, such as hazards, environmental pollution, corrosion, growth of bacteria and/or viruses in the heater shell, short life span, maintenance necessity, temperature fluctuations.…”

Original scientific paper In this study, an induction air heater prototype that is designed to supply hygienic air was analysed. The purpose of this paper is to determine the distribution of energy losses and investigate the effects of inducer discs on the thermal efficiency of the prototype. The analysis was carried out by applying the 1st Law of Thermodynamics. In the study, the natural convection and radiation losses, the discharge losses and the losses due to kinetic energy were calculated and presented. The maximum thermal efficiency was calculated to be 29,9 % without discs. It was seen that, to ensure the competitiveness of the induction air heater among other air heaters, the thermal efficiency can be boosted up to 90 % with appropriate insulation and construction. It was seen that utilizing the discs decreased the efficiency and the total energy loss was reduced as the number of discs was decreased. Analiza učinkovitosti indukcijskog grijača zraka i ispitivanje raspodjele gubitaka energijeIzvorni znanstveni članak U ovom se radu analizira prototip indukcijskog grijača zraka konstruiranog za dovod higijenskog zraka. Cilj je rada odrediti raspodjelu gubitaka energije i ispitati učinke diskova na toplinsku učinkovitost prototipa. Analiza je provedena primjenom prvog zakona termodinamike. U radu su izračunati i prezentirani gubici zbog prirodne konvekcije i zračenja, gubici ispuštanja i gubici zbog kinetičke energije. Izračunato je da je maksimalna toplinska učinkovitost 29,9 % bez diskova. Ustanovljeno je da, kako bi se osigurala konkurentnost indukcijskih grijača zraka u odnosu na druge grijače, toplinska učinkovitost se može povećati do 90 % odgovarajućom izolacijom i konstrukcijom. Ustanovljeno je da primjena diskova smanjuje učinkovitost i ukupni se gubitak energije smanjio smanjenjem broja diskova.Ključne riječi: indukcijski grijač fluida; povećanje energetske učinkovitosti; toplinska učinkovitost; učinkovitost Prvog zakona; zagrijavanje indukcijom; zagrijavanje zraka indukcijom
