Double integral sliding mode control of paralleled dc/dc converters

The use of dc-dc converters connected in parallel is a suitable way to solve the technological problems that arise in large-capability power supply systems. This paper presents a new approach to parallel converters using double integral sliding mode control. This approach could alleviating the steady-state regulation error and enhancing dynamic current-sharing property by increasing the order of the proportional integral sliding mode (ISM) controllers using an additional integral term. Theoretical analysis and simulation results are provided for verification.
