The present invention relates to power supplies modules for distribution automation system and more particularly to provision of power supply in remote input output devices such that more than one power supplies modules may be effectively connected together. Power supply modules connected together in parallel, with common or independent input sources, share the load proportionally (equally) by load share control. The parallel modular power supply system are coupled at input, output and for load sharing control have interferences/cross talks amongst them, causing difficulty in achieving stability over the entire range of operations specially with independent input sources having wide differences in the input voltage levels. The invention provides for effective decoupling of power supply modules and improved stability by use of a filter amplifier component to reduce the effect of noise in the power supply module in the secondary side within the power supply module. The power supply module for distribution automation system also provides a means to indicate and communicate health status from each of the power supply modules connected together. |
