Construction of power systems based on a group of power electronicsmodules is of interest to enterprises with a wide range of load capacities that require power at frequencies different from the general industrial. The advantages of this method are possible to get the required power source, using a limited set of power modules, reducing the cost of redundancy, quickly adaptationof inverter to the magnitude and nature of the load. Among the problems of the theory and practice of group one of the main transformers is to provide high-quality source of transients with load and supply voltage. The paper presents a mathematical model of a double-bridge inverter group on the basis of single-phase inverter power supply for varying over a wide range of active-inductive load. The model is designed to study the dynamics of the automatic load sharing between the components of the inverter modules.
