Sliding Mode Based Control of Dual Boost Inverter for Grid Connection

Single-stage voltage step-up inverters, such as the Dual Boost Inverter (DBI), present a large variable operating range, which together with the non-linearities of the converter, makes them a challenge to control. This paper presents a global current control method based on a combination of a linear proportional resonant controller and a non-linear sliding mode controller that simplifies the controller design and implementation. The proposed control method is validated using a grid-connected laboratory prototype. Experimental results show the correct performance of the controller and compliance with power quality standards.
