Other Parts Discussed in Thread: UCC28070A
The circuit above is a circuit that I arbitrarily designed using UCC28064A.
PFC circuit specifications
Input voltage : AC220V
Output voltage : 400V
Output power : 3.3kW
We will test with an open loop before mounting on a PFC circuit.
We are only experimenting with the controller circuit for open loop operation.
PWM waveforms are not coming from the GDA and GDB pins.
1. Which part of UCC28064A pin should you apply voltage to the PWM circuit?
2. Is PFC designed with UCC28064A not open loop operation test?
Please Help me.
