ANALYSIS, DESIGN AND MODELING OF DC-DC CONVERTER USING SIMULINK By SAURABH KASAT Bachelor of Engineering Institute of Engineering and Technology Indore, Madhya Pradesh State India Submitted to the Faculty of the Graduate College of the Oklahoma State University in partial fulfillment of the requirements for the Degree of MASTER OF SCIENCE. The power supply is rated at 100W maximum output power. The converter produces sinusoidal output waveform with respect to magnitude [V], frequency [rad/s] and phase [a,b,c] witch help from a DC-power supply. Here is the simple inverter circuit diagram using 555 timer IC. Volt meters to 600V,AC, current meters to 5A. 12v DC to 220v AC Converter for home, car or your school. The circuit is easy to make and is low cost. of a DC/DC Converter generally increases as its load increases. The aim of this circuit is to supply AC power similar to the one that we receive at homes. 1: Abstract functionality of a DC-DC Power Converter: an unregulated input voltage is transformed into a regulated (i. All these power supplies have one thing in common - they take high voltage 120V or 220V AC power and regulate or convert it down to say 12V or 5V DC. 2 The purpose of an AC Voltage Controller, or AC Regulator, is to vary the RMS voltage across the load at a constant frequency.
