Abstract
Ovaj rad opisuje postupak projektiranja četiri rezonantna prekidačka pretvornika snage frekvencija 650 kHz te 5 MHz, 10 MHz i 20 MHz. Rezonantni pretvornici imaju mnogo prednosti ali i mana u odnosu na linearne i klasične prekidačke pretvornike. Budući da rezonantni pretvornici mogu optimalno raditi samo na jednoj frekvenciji, potreban je pravilan odabir vrijednosti kondenzatora i zavojnica kao i ostalih elemenata čiji parametri mogu utjecati na rad. U radu je opisan postupak rješavanja sustava diferencijalnih jednadžbi koji opisuju rad sklopa po pojedinim fazama, a kao konačno rješenje dobiju se vrijednosti pojedinih kondenzatora i zavojnica koje osiguravaju optimalan rad sklopa. Za rješavanje su korištene svojstvene vrijednosti i svojstveni vektori. Na kraju je projektiran rezonantni DC-DC pretvornik frekvencije 650 kHz koji pretvara 5 V na 3.3 V, te tri pretvornika frekvencija 5 MHz, 10 MHz i 20 MHz koji pretvaraju 12 V na 5 V. Mjerenjem je prikazano ponašanje pojedinog rezonantnog pretvornika snage. Konkretno, mjereni su karakteristični valni oblici u vremenskoj domeni, izlazni naponi te vođene i zračene elektromagnetske smetnje.
Abstract (english)
This paper describes the design of the 650 kHz and 5 MHz, 10 MHz and 20 MHz resonant switching converters. The resonant switching converters have many advantages but also disadvantages in comparison to linear and switching converters. Since the resonant switching converters can only operate at one single frequency, the values of capacitors and inductors, as well as other elements, must be correctly calculated. Also, this paper describes the procedure for solving the systems of ordinary differential equations (ODEs) that describe the operation of the circuit for each phase. As a final solution of this systems of equations, the values of capacitors and inductors are obtained, which ensure optimal circuit operation. The method of eigenvalues and eigenvectors is used to solve the system of ODEs. At the end, the 650 kHz resonant converter which converts the DC voltage from 5 V to 3.3 V and 5 MHz, 10 MHz and 20 MHz resonant converters which convert the DC voltage from 12 V to 5 V are designed. The measurements show the behaviour of each resonant switching converter. Specifically, the characteristic waveforms in the time domain, the output voltages and radiated and conducted emissions are measured.
