Small-Signal Analysis and Voltage Mode Controller Design for Active-Clamp Forward Converter

Optimized Fuzzy Controller Design in Unbalanced Voltage Drop Mode for Dynamic Voltage Restorer

The loss of balanced voltages involves a voltage drop due to symmetric three-phase errors, or the initiation of high-power three-phase loads or symmetric three-phase switches. While these events in an unbalanced way lead to asymmetric voltage drops. Voltage drops can cause asymmetric load on the power grid, the occurrence of volatility, and even network power outage. One of the most common ways...

Design and Implementation of a Constant Frequency Sliding Mode Controller for a Luo Converter

In this study, a robust controller for voltage regulation of the POESLL converter worked in continuous conduction mode is presented. POESLL converter is a DC/DC converter with a high voltage gain. DC/DC converters are used in telecommunication systems, power sources and industrial applications. Owing to the switching operation, the structure of the POESLL converter is highly non-linear. In addi...

Small-signal Stability Analysis and Vsi Controller Design for Microgrids Operating in Grid-connected Mode

A novel approach for VSI with an LCL output filter controller design for microgrids operating in grid-connected mode is presented in this paper. The controller structure is based on a multiloop control configuration in which the inner control loop is responsible for current regulation and the outer control loop generates the reference currents based on preset active and reactive power injection...
