Abstract
Ovaj završni rad bavi se pobuđivanjem ultrazvučnog pretvarača rezonantnim pretvornikom veće snage. Definirani su parametri ultrazvučnog polja kako bi se razumio rad ultrazvučnog pretvarača. Izmjerena je električna impedancija ultrazvučnog pretvarača kako bi se odredila rezonantna frekvencija na temelju koje se mikrokontrolerom generira pravokutni pobudni signal. Objašnjen je način dobivanja pobudnog signala s odbrojavanjem sata u sustavu i modulom za modulaciju trajanja impulsa. Signal generiran mikrokontrolerom nema dovoljnu snagu za pobuđivanje ultrazvučnog pretvarača zbog toga je u radu obrađeno pojačalo snage klase E na koje se spaja izlaz mikrokontrolera.
Abstract (english)
This BSc thesis considers the excitation of ultrasound transducer by using a high power resonant converter. Parameters of the ultrasound field are defined to understand the operation of the ultrasound transducer. The electrical impedance of the ultrasound transducer was measured to determine its resonant frequency. Rectangular excitation signal of the same frequency as the resonant frequency is generated by the microcontroller. The method of generating an excitation signal with a system timer or pulse width modulation module is explained. The signal generated by the microcontroller does not have enough power to excite the ultrasonic transducer and that is why the signal has to be amplified. In this thesis class E resonant power converter with zero voltage switch is analyzed.
