Abstract
U završnom radu izrađen je i ispitan istosmjerni silazni istosmjerni pretvarač koji ima regulaciju istosmjernog napona od 4.5 do 40 V uz izlaznu struju do 2 A. Analiziran je rad silaznog istosmjernog pretvarača koji radi u dva režima rada: kontinuirani i diskontinuirani režim rada pri velikoj frekvenciji uz valovitu ili glatku struju. Opisan je postupak izrade silaznog istosmjernog pretvarača, te njegovi podsustavi: prednosti i nedostatci, te princip rada pretvarača. Postupak testiranja obavljen je u dva mjerenja uz mijenjanje karakterističnih parametara. U prvom mjerenju mijenjan je otpor trošila, a u drugom mjerenju mijenjan je ulazni napon dok je izlazni konstantan. U postupku testiranja izmjerena je frekvencija rada pretvarača, te određena valovitost izlaznog napona.

Parallel abstract (English)
In the final work was developed and tested Step-down DC converter with a DC voltage regulation of 4.5 to 40 V with an output current up to 2 A. We analyzed the operation of step-down DC converter that works in two modes: continuous and discontinuous operation at high frequency with wavy or smooth power. We described the procedure of making the step-down DC converter, and its sub-systems: advantages and disadvantages, and the principle of the inverter. The testing procedure was performed in two measurements with changing characteristic of parameters. In the first measurement we changed resistance load, and in the second measurement we changed the input voltage and the output voltage was constant. In the process of testing measured the frequency of the inverter, as well as specific output voltage ripple.
