| Abstract: | Adopting modular power supplies to construct a distributed power system can improve the reliability and quality of the system.A 28 V/36 A prototype modular power supply using three-dimensional stacked-layer structure was built.Phase-shifted zero-voltage-switching PWM full-bridge converter was employed as the main circuit.The parasitic parameter model of the modular power supply was built and the optimization strategies of improving the electro-magnetic compatibility performance were proposed.The electrical performance of the module was tested and the experimental results were given.Finally,loss analysis and the temperature distribution simulation result using Flotherm are included.The package has better thermal management. |
