Single phase seven level Z-source cascaded H-bridge inverter for photovoltaic systems

Abstract

<p>The Multilevel inverter (MLI) is identified as a viable power electronic unit for distributed energy conversion applications. In this paper discusses the performance of single phase seven level Z (impedance) source cascaded H-bridge inverter topology suited for solar photovoltaic systems. A modified sinusoidal pulse width modulation technique is used to control the switches of the H-bridge inverter. The simulation results are obtained interms of inverter output voltage and harmonic analysis confirm improvement in voltage boost and reduction in harmonic distortion of the suggested inverter topology. The experimental results matches with the simulation values, as verified through a scaled down prototype.</p>

“…The transmitter side will be on the ground and the receiver's side will be in the vehicle. To get supply to the transmitter side, the utility grid of alternating current (AC) supply is converted Int J Adv Appl Sci ISSN: 2252-8814  A receiver-side power control method for series-series magnetic topology in … (Bhukya Bhavsingh) 235 to direct current (DC), such that constant DC voltage is given to the high-frequency DC to the AC basic H-bridge inverter [10], [11]. The sending and receiver coil in the WPT system has weak coupling because of the distance between vehicle ground clearances.…”

“…Receiver current I2 can be found in (11), that the RMS value is independent of the output voltage (VCD), also it depends on the supply voltage (VAB), and mutual inductance (M). The S/S compensated wireless charger is a constant current source and can be controlled by the supply voltage in general [27]- [31].…”
