This paper proposes two methodologies that are extended from the existing Cascaded Multilevel Inverter Employing Three-Phase Transformers and Single DC Input topology . The proposed circuit configuration can reduce the number of switches required to convert the input DC power into AC power when compared with traditional method. However Simulation results reveals that the THD variation of the pr...

An ultra-high gain DC-DC converter with single-switch structure is introduced in this paper. Full soft-witching provided by simultaneous use of quasi-resonant performance one resonant tank and leakage inductance a three-winding coupled inductor (CI). Adopting the secondary tertiary windings CI separated voltage multiplier cells enables to provide gain. The reverse recovery problem resolved than...

The control of the input voltage of DC-DC converters is frequently required in photovoltaic applications. In this special situation, unlike conventional converters, the output voltage is constant and the input voltage is controlled. This paper deals with the analysis and the control of the buck converter with constant output voltage and variable input.

In this paper, a novel parameter design approach of the PI controller used for individual DC voltage balancing control of cascaded H-bridge converter-based STATic synchronous COMpensator(STATCOM) is presented. By means of phase shift sinusoidal pulse width modulation, using two control loops(DC voltage control loop and phase angle shift control loop) to ensure DC voltage balance, the proposed a...

This paper presents research results related to the concept of a high-voltage-gain DC-DC converter with low input current ripple. In proposed topology, low-volume switch-mode boost operates in parallel switched-capacitor voltage multiplier (SCVM). The overall achieves four-fold gain, but stress transistor and diode is only half output voltage. achieved by applying specific topology converter. F...

Renewable energy system (RES) based microgrid applications have grown extensively over the recent years. Owing to power fluctuations in RES, acquiring stable and accurate output voltage at DC Bus is a major concern applications. Presently, switching, as well as, prediction of for RES quite slow total harmonic distortion cannot be reduced minimal level. Accordingly, this research developed contr...
