Sliding mode control of a three-phase four-wire LCL rectifier

In this paper a control algorithm for a three-phase four-wire rectifier with an inductive-capacitive-inductive filter is presented. The control scheme consists in an inner current loop designed using the Sliding Mode Control technique, and an two external loops that regulates the DC bus voltage and also keeps the split bus balanced. Numerical simulations are also provided to show the performance of the closed loop.
