Hello.
I designed a half bridge converter by using tl494 chip. and so it's 2pole - 2zero compensation network.
but this configuration is suitable for inverting error amp configuration not non inverting like tl494. Now I confused how to solve this problem for make circuit to be stable!
Actually using a RC feedback in non inverting configuration same as in ATX power supply(that use tl494 not SG series),just make one pole (at origin) and one zero.It make overall loop -2 slop at cross over frequency not -1. how it is possible to be stable? although there is not any instability in ATX !!!
