Digital Simulation of Photo Voltaic Based Cascaded Boost Converter for Voltage Source Inverter fed Induction Motor Drive

Solar energy is one of the important infinite source that maintains life on earth and is of clean energy. This energy can be converted to different forms as per our requirements. In this paper digital implementation of Photo Voltaic (PV) based cascaded boost converter (CBC)for voltage source inverter (VSI) fed induction motor is presented. The proposed PV model is based on a behavioral cell mod...

Genetic Algorithm Based Solution in Pwm Converter Switching for Voltage Source Inverter Feeding an Induction Motor Drive

Magnetically coupled high-gain Y-source isolated DC/DC converter

A new form of magnetically coupled DC/DC converter is proposed for medium power applications (250 W to 2 kW), requiring a high-voltage gain, short inductive charging time and galvanic isolation. The proposed converter can be realised using a unique Y-source impedance network and a two-switch push–pull circuit with voltage-doubling rectification. The converter’s voltage gain is presently not mat...

Augmented Sequence Impedance Networks of Grid-tied Voltage Source Converter for Stability Analysis

Impedance-based stability analysis normally splits an interconnected system into source and load subsystems and the stability of the closed loop system can be analyzed by the combined input-output gains of source and load. This is an intuitive approach in the case of Single-Input Single-Output (SISO) systems. However, in the case of grid-tied voltage source converter (VSC) systems, dq impedance...

High Efficiency Isolated AC/DC Converter with Gradationally Controlled Voltage Inverter for On-board Charger

We have developed a new isolated AC/DC converter for electric vehicle on-board chargers. It consists of an AC/DC converter with Gradationally Controlled Voltage Inverter (GCVI AC/DC converter) and an isolated Zero-Voltage-Switching (ZVS) DC/DC converter, each of which is optimally controlled to convert in a highly efficient means. As a result, the new on-board charger has achieved a power conve...
