Design and simulation of high-power power conditioning unit with Matlab

Modeling and simulation play an important role on the design and analysis of the high-power power conditioning unit.For the 20 kW power conditioning unit,a modular system with a full regulated main-bus was designed.Using the Matlab/Simulink software,a simulation system was established,which contained sequential switching shunt regulators and battery charge/discharge regulators.With appropriate circuit parameters and control parameters,steady and dynamic responses of main-bus were simulated under various working conditions.Simulation results show that the designed power conditioning unit can meet the requirement of the 20 kW payload.
