| Abstract |
High power supply systems must be carefully designed in order to maintain their performance, compared to that of low power systems. There is a trend to use several standard DC-DC converters connected in parallel to solve this problem. These converters help to reduce the costs and to improve the productivity in the facilites where they are used. This paper describes two methods to connect several DC-DC power converters to form a high power supply system so that they achieve the basic requirements of this system. The "averaged voltage mode control" and the new method "synchronized voltage mode control" permit to share the total load current of the power supply system equally between the different power modules using voltage mode control. Both methods are compared with classical methods in the case of three buck converters (12V,5A) connected in parallel operation. The system has been simulated using the PSPICE V4.02 of MicroSim Corporation. For the synchronized voltage mode control, the simulated results are compared with experimental results. |
