<p><span lang="EN-US">Nested neutral point clamped multi level inverter with inter connection to grid through the synchronous reference frame (SRF) controller for synchronization of voltage is demonstrated. The system's main feature that stress in each switching device kept a minimum, and redundant states are utilised flying capacitor balancing sinusoidal pulse-width modulation (PWM...

This paper explores Switched Inductor (SL) Zsource inverter which adjusts the voltage and have application in Fuel cells (FCs) which have achieved global attention as an alternative power source for hybrid electric vehicles (HEVs). The proposed inverter uses inductor and capacitor circuit to join the source and load circuit. On comparing with the initial Z-source inverter, the explored circuit ...

This paper presents a hybrid modulation technique consisting of singe-reference six-pulsemodulation (SRSPM) for front-end dc/dc converter and 33% modulation for three-phase inverter. Employing proposed novel SRSPM to control front-end dc/dc converter, high frequency (HF) pulsating dc voltage waveform is produced, which is equivalent to six-pulse output at 6× line frequency (rectified 6-pulse ou...

Flying capacitor multi-level converters use charged capacitors as a critical element. For proper operation, the voltages must be known and regulated. Direct measurement is straightforward, but when number of required measurements high, this complicated approach. This paper introduces an estimation method for n voltages. The scheme based on system ( + 1 ) equations, which defined in way that it ...

In this paper, a high frequency contactless power transfer (CPT) system is designed with ∅2 inverter drive. This system works in 30MHz frequency and 380W power with low voltage stress and considers the inductive link parasitic capacitor effect. In the design, we formulated the inverter equations first and then suggested another design for the transmitter and the receiver coils as the energy tra...

The main objective of this project to control the common mode leakage current by using virtual dc bus with PV systems. The power which we receive form the PV panel is not a constant supply due to various condition. In order to overcome this issue we are using Buck Boost converter for generating constant voltage supply to the inverter. The negative pole of the dc bus is connected directly to the...
