This paper describes a discrete adaptive state feedback controller used to load current control in terms of variable DC voltage of inverter. Controller was designed by using linear quadratic optimization method. Adaptive LQR was used because of non-stationarity of the control system caused by Voltage Matching Circuit VMC. Gain values of the adaptive controller were approximated by using an arti...

Voltage fed single stage converters suffer from two main drawbacks: The efficiency is affected due to the reduced values of maximum DC link capacitor voltage and the power factor is not close to unity. To overcome these drawbacks, a boost type input current shaping converter, integrated with diode clamped topology is used. S ince this converter is a multilevel converter, it can be operated with...

DC-DC converters are switched power converters. They are used to convert one DC voltage to another DC voltage. It is inordinately used in industry as well as in research. The model of converter system varies from the ON state to the OFF state. The major drawback of the boost converter is the uncontrolled supply of voltage and current. So initially a convectional PID controller is designed to re...

In this paper for finding the best value of duty ratio for switches to minimize the THD, the GA algorithm has been used and THD output voltage is assumed to be fitness function. The proposed voltage regulator employs multi-level AC/AC converter to generate compensation volt...

Voltage sag is a serious power quality problem affecting domestic, industrial and commercial customers. Voltage sags may either decrease or increase in the magnitude of system voltage due to faults or change in loads. In this paper a switch mode AC BuckBoost regulator is proposed to maintain voltage across a medium size domestic appliance constant during long period of voltage deviation from th...

In this paper mainly presents about the DSTATCOM and control methodology of DC capacitor voltage, generally, the dc capacitor voltage is regulated using a PI controller when various control algorithms are used for load compensation.

Both Soft computing based controllers and sliding mode controllers have been utilized to regulate the output voltage of dc-dc converters in response to changes in the load and the input voltage. Although both control techniques possess desirable characteristics, they have disadvantages which prevent them from being applied extensively. Many researchers have proposed the combination of sliding m...
