Study on the voltage stability of multi-output converters

With the development of electronic technology, multi-output power supplies with different output voltage levels and load capacities are required, and using multi-output DC/DC converters is an effective and economical method. In this paper, the cross regulation of multi-output converters is analyzed in theory, and the coupling relations of different outputs are also deduced, and then a kind of post regulation based on synchronous rectifiers is presented to achieve precisely regulated multiple outputs. The results of simulation and experiment verify that the method has a lot of advantages such as simplicity of topology, convenience of control, highly stability of outputs and so on, so it is a practical multi-output project for switch mode power supplies.
