Due to the more applications of impedance source inverters and removal of its limitations, many topologies have been suggested based on this inverter of which one of these proposed topologies is based on impedance source inverter with switched inductor (SL). This proposed topology has solved the problem of D and M interference in the initial impedance source. Today, PWM-based single-phase inverter pulse width modulation which is used in unceasing power distribution, must provide loads in a non-linear and critical condition. With regard to the fact that inverter output impedance is not zero, these loads destroy the sinusoidal output voltage. Controller should form a good regulation to the output voltage against sudden changes of input voltage and output current. These needs imply to use fast controller with favorable dynamic reaction to converters. One of these nonlinear control methods is the indirect adaptive controller which is based on the LIAPANOUVE method, providing stability function. In this article, indirect adaptive controller for single-phase inventor of impedance source with switched inductor is designed for controlling its voltage in order to use in distributed generation sources and has been simulated to verify proper controller operation on proposed inventor of the controller designed in Matlab / Simulink application.
