This project was about choosing a problem, find several solutions and finally implement the best solution which this report will be about. In our case the problem occurs in the PFC (Power factor correction) circuit which located between the rectifier and the inverter in the UPS device. The Power factor correction shapes the input current of off-line power supplies to maximize the real power available from the mains. There was a thermal damage because of the over voltage that effect the power factor of the circuit. To solve this issue I chose to apply the first solution which is replacing the IC (integrated circuit) and implement a circuit to raise the power factor.
