Abstract:V diplomskem delu sta obravnavana dva tipa indukcijskih kuhališč, ki imata različen način regulacije izhodne moči. Pri prvem kuhališču se spreminja moč na tuljavi s spreminjanjem stikalne frekvence, pri drugem pa je ta frekvenca stalna in se spreminja preklopno razmerje toka skozi tuljavo. Pri obeh kuhališčih so bile izmerjene izgube, ki nastajajo v močnostnem delu elektronike. Omenjene izgube so bile merjene na elementih, kot so EMI filter, usmerniški mostič, IGBT-ji in kontrolna plošča z ventilatorjem. Za merjenje izgub je bil uporabljen digitalni LeCroy Wavepro osciloskop z ustrezno SW in strojno opremo. Rezultati meritev so prikazani tabelarično in grafično.

Title:Evaluation of the loss of induction cooker system with half-bridgeable resonance circuit and the different methods of regulation of output power
Abstract:In this diploma work two types of induction hobs with two different manners of output power regulation are discussed. Power change of the first hob is generated on the coil by changing the switching frequency, whereas with the second hob said frequency is constant, but the switching ratio of the coil current shifts. Power waste present in power electronics was measured in both hobs. The measurement of waste was conducted on elements such as the EMI filter, rectifier bridge, IGBTs, and control panel with fan. Digital LeCroy Wavepro osciloscope with suitable SW and hardware was used during the process of measuring the waste. The results of the measurements are shown both tabularly and graphically.
Keywords:induction heating, cooker coil, induction hob, half – bridge resonant inverter, quasi – resonant inverter, induction waste, waste on semi-conductor elements
