INTRODUCTION

DIFFERENT TYPE OF DC -AC INVERTERSSquare wave inverter

Modified sine wave inverter

Pure sine wave inverter.

• PROJECT FOCUSES ON DC TO AC CONVERSION.

• THIS PROJECT FOCUSES ON PURE SINE WAVE GENERATION

METHODOLOGY

CONVERSION FROM DC-AC.I. LVDC-LVAC THEN STEP UP TO HVAC. II. LVDC-HVDC THEN CONVERTING TO AC.

THIS PROJECT FOCUSED ON THE 1ST METHOD

APPLICATION

INVERTERS ARE USED FOR MANY APPLICATIONS, AS IN SITUATIONS WHERE LOW VOLTAGE DC SOURCES SUCH AS BATTERIES, SOLAR PANELS OR FUEL CELLS MUST BE CONVERTED SO THAT DEVICES CAN RUN OFF OF AC POWER. ONE EXAMPLE OF SUCH A SITUATION WOULD BE CONVERTING ELECTRICAL POWER FROM A CAR BATTERY TO RUN

• LASER PRINTERS.• LAPTOP COMPUTERS.• POWER TOOLS.• DIGITAL CLOCKS.• MEDICAL EQUIPMENT.• TV AND CELL PHONES.
