1ф PWM Sine wave Inverter

  1. 1. 1Ф PWM SINE WAVE INVERTER BY: MOHAN K M SHIVARUDRAPPA G GANESH C UNDER THE GUIDANCE OF MRS. GAYATHRI DEVI B ASSISTANT PROFESSOR DEPARTMENT OF ELECTRICAL AND ELECTRONICS ENGG PESIT
  2. 2. INTRODUCTION • PROJECT FOCUSES ON DC TO AC CONVERSION. Square wave inverter DIFFERENT TYPE OF DC-AC INVERTERS Modified sine wave inverter Pure sine wave inverter. • THIS PROJECT FOCUSES ON PURE SINE WAVE GENERATION
  3. 3. METHODOLOGY  CONVERSION FROM DC-AC. I. II. LVDC-LVAC THEN STEP UP TO HVAC. LVDC-HVDC THEN CONVERTING TO AC.  THIS PROJECT FOCUSED ON THE 1ST METHOD
  4. 4. BLOCK DIAGRAM • DC LOW VOLTAGE TO LOW VOLTAGE AC THAN STEP UP TO HIGH VOLTAGE Constant/Variabl AC e DC Source INUT 12V DC MOSFET DRIVE SINE WAVE GENERAT OR TRIANGLE WAVE GENRATOR PULSE GENRATOR MOSFT H-BRIDGE FILTER PURE SINE WAVE OUTPUT
  5. 5. Design of each block  sine wave generator **  triangle wave generator **  Bridge **  Mosfet driver **  Filter **
  6. 6. CIRCUIT DIAGRAM**
  7. 7. 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.
