Other Parts Discussed in Thread: UCC27324, TL431
Hi,
I have been working with TL494 recently for my bachelor project at university. I have designed a push-pull converter which boosts up 12VDC to 340VDC after rectification. The problem that I faced is that the output voltage drops significantly when I add load to the circuit. For example, if the load pulls 100 ma, the output voltage drops 310V from 340V. if the load pulls 200ma, it drops to 270V. I have used electronic loads and resistive load, it gives me the same results. The design is vital for my project. So, I would really appreciate your help.
Kind Regards
