Abstract :
A sliding-mode control using a new sliding surface just depending on the output voltage is proposed for the boost inverter. It overcomes some disadvantages that the traditional sliding-mode control has. The surface is derived from the current-mode control idea of indirectly controlling the output voltage through the inductor current. The controller has a fast response, is robust under load and input voltage variations, and yet is remarkable simple to implement. Although it is strongly nonlinear, it can be implemented using standard electronics circuitry and only needs voltage measurements. Unlike the common approach of generating a sinusoidal voltage in both capacitors of the inverter, the strategy here proposed, focuses on generating a sinusoidal voltage on the load despite the capacitors voltage form. As a consequence, the desired output voltage is just necessary as a reference to implement the controller
