Parallel inverters are often used to meet system power requirements beyond the capacity of the largest single structure. They have also been used to reduce harmonics, reduce PWM switching frequency and increase available output voltage or frequency. The type of parallel structure depends on the construction of the load motor, the most prevalent are dual three phase machines, split-phase machine...

To efficiently supply wide-range DC voltage from a pulse-width modulation (PWM) rectifier, this paper presents a single-phase, full-wave, diode-bridge, single-ended primary-inductor converter-type (SEPIC-type) power-factor-correction (PFC) rectifier in continuous conduction mode with a sliding surface-regulated current-mode PWM controller. According to the switched-mode operation of the rectifi...

Abstract Modular Multilevel Converter (MMC) has found very wide application in renewable energy sources, DC power transmission, high voltage applications and micro grid. However the technical challenge of MMC is to maintain constant current, constant power and constant voltage at the output depending on the requirement. In this paper a control loop is developed for maintaining constant power at...

This paper proposes a single-phase five-level photovoltaic (PV) inverter topology for grid-connected PV systems with a novel pulse width-modulated (PWM) control scheme. Two reference signals identical to each other with an offset equivalent to the amplitude of the triangular carrier signal were used to generate PWM signals for the switches. A digital proportional–integral current control algori...

circuit of the power supply in pulse width modulated (PWM) voltage inverters results in output voltage deviations. Although individually small, when accumulated over an operating cycle, the voltage deviations are sufficient to distort the applied PWM signal. This paper presents a new method to correct for the dead time deviations. The Pulse Based Compensator is less hardware and software intens...
