A power supply control is disclosed which performs in conjunction with an a.c. source as may be provided by a utility line input. This line input is directed through a converter which reflects or mirrors an a.c. signal into the line input mimicing it in all aspects except that of amplitude. The opposite side of the bi-directional device is coupled to a node connection which further is coupled to an energy reservoir present as a rechargeable storage battery. An output converter device serves to develop a desired a.c. output employing the energy at the node connection. Energy transfer into the node is provided by controlling the amplitude of the input converter such that it is slightly less than that of the input utility. The apparatus is modular in design such that it may assume a variety of configurations employing either a.c. or d.c. node connections.
