Abstract :
A sliding mode control for a boost type three phase rectifier is presented. A new mathematical model whose state variables are the amplitude and the phase of the input current is achieved. Several problems related to the controller design are dealt with: a sliding manifold shaping which avoids the absence of permissible control configurations during start up operating conditions is proposed; the PWM pattern optimization problem is considered and a method for the switching frequency reduction is presented; the output feedback control and the closed loop stability are analyzed. Simulation results are also provided
