the process will use circuit simulation software to test program. Then, according to the actual situation for multi output switching power supply circuit simplicity and safety requirements, the design of the bus DC converter and reasonable fixed duty ratio control circuit, it still can be very good to the realization of the basic functions of the circuit in the case of less peripheral circuit, but also can meet the requirement of the protection circuit design. Then, in order to ensure the recovery system of the launching of the two in the process of normal transition in electric start and failure, there will be on the bus DC converter and a fixed duty cycle start process control circuit in detail, at the same time both practicality and reliability requirements, construction starting circuit. Finally, according to the design index of the actual prototype, the design process of the circuit parameters is given, and the overall performance of the prototype is tested by experiment, so as to prove the feasibility of the whole scheme.
