Dear sir,
i designed this circuit for 70W
primary inductance is 500uH
primary turns 80 turns
core gapped ee30 core
output_ 15V/0.7A(6turns)
output_ 5V/1.3A(3turns)
output_ -9V/0.3A(4turns)
output_ 24V/0.7A(10turns)
output_ 15V/0.7A(6turns)
this circuit is not operating with constant duty ratio with loading also. frequency skipping is happening please suggest some solution sir
