A Hybrid Switching Technique for Single-Phase AC-Module PV System to Reduce Power Losses and Minimize THD

This paper proposes a hybrid switching technique for a domestic PV system with AC-module architecture. In this PV system, independent control of PV modules, which are directly connected to DC terminals of a single-phase cascaded multilevel inverter, makes module-level MPPT possible to extract maximum available solar energy, especially in partial shading conditions. As one of the main contributi...

FPGA Based Speed Control of AC Servomotor Using Sinusoidal PWM

This paper presents a Xilinx Field Programmable Gate Array (FPGA) based speed control of AC Servomotor using sinusoidal PWM technique. Xilinx FPGA is a programmable logic device developed by Xilinx which is considered as an efficient hardware for rapid prototyping. It is used to generate 50 Hz sine wave, the triangular wave and the sinusoidal PWM signals. The sinusoidal pulse width controls the...

A New Simple Single Phase AC-AC Switching Voltage Regulator Cum Power Conditioner

A new very simple single phase ac-ac voltage regulator based on LC network is proposed here that compensates wide range supply voltage variations. This has the capability of both buck and boost the input source voltage level without any change of phase angle. The number of components used in the converter circuit is minimum and smooth output waveform can be achieved without any additional filte...

A Zero Current Switching Ac-Ac Resonant Converter for Three Phase Induction Heating

This paper proposes the concept of three phase ac to ac resonant converter for Induction heater. As compared with basic converters, ac to ac resonant converter has advantages of less components count, low cost, high reliability and better efficiency. A closed loop control structure is proposed in this paper for controlling three phase resonant converter. Finally, this proposed system is experim...
