Project Results
Project Goals

• Graph represents Power Efficiency and Cost
  Effectiveness
• Power Efficiency is attained as the voltage
  output is the same for
• both transistors
• Cost Effectiveness is also achieved as our
  current transistor,
• SPP20N60C3, cost approximately a third less
  than our original transistor,
• SPP02N65C3

• We designed a Modular DC-AC Inverter for
  Alternative Energy
• Residential Applications
• Our objectives were to develop a more power
  efficient and cost
• effective model than the original researched
  inverter

• Circuit (breadboard) Prototype
• Our Circuit utilizes SPP02N60C3 and
  successfully lights up a LED to
• indicate functionality

Project Overview

• Circuit Schematic
• Our final circuit schematic included a LC filter
  which helped us
• obtain a smooth sinusoidal output
• If we use a solar cell as a load across
  CBOOSTER, we can then
• use the inverter for residential applications

Project Conclusions

• Our objectives of Power Efficiency Cost
  Effectiveness were achieved
• We used PSpice to simulate Hierarchical Blocks
  in order to obtain
• greater power efficiency
• The output frequency of the inverter is 60Hz
• The input voltage from alternative energy source
  is registered at
• VIN0.7VDC
• The output voltage achieved for an individual
  prototype is VAC0.9 VRMS
• Our inverter circuit successful functionality
  was indicated by our LED
• lighting up as a load across CBOOSTER
• On replacing the LED with a solar cell, the
  inverter can be applied for
• residential use
• We learned to work effectively in a team
  environment
