Loop Compensation Design Method of a Flyback Magnetic Insulation Switch Power Supply
A loop compensation design method of a flyback magnetic insulation switch power supply is introduced.Firstly,the small signal trausfer function of the flyback magntic insulation switch power supply was established.Then,the design parameters of the feed back loop were qualitatively analyzed and quantitatively calculated.The appropriate phase margin and gain magin were designed.Finally,a simulation analysis model was built and the experimental verification circuit was conducted.The results prove that the adapted design method is feasible and has good universality.
