The enhancement of multilevel converter for coaxial inductive power transfer in low voltage DC power distribution

Defibrillators are electronic devices that carry shock electrical signals (pulses) to the heart muscle to maintain myocardial depolarization that is undergoing cardiac fibrillation (ventricular fibrillation or atrial fibrillation) (Bronzino, 2000). There are several conditions that must be met for the occurrence of shock processes including shock time, energy to be provided, patient and operator safety. In this defibrillator the use of selectors / energy selection is linear in the range 1-30 Joules with the use of tools at 10, 15, 20, 25, 30 Joules. The energy will then be discarded or given to the patient via a paddle when pressed the Discharge / shock button. The result of the signal given to the patient is monophasic. This study used a pre-experimental type with a One Group post test design research design. Measurements were made 5 times the volt meter at the test points determined by the compiler.

“…The most explored technologies are hydroelectric technology, wind system technology, nuclear technology, and photovoltaic technology. Due to the shortage of fossil fuels and the negative impact of some energy production technology on the environment, the advancement of power electronics introduces a new class of power converters known as multilevel converters in high and medium power voltages applications so that it can assist the electrical grid to solve this issue of high electricity demand [1]. Multilevel inverters or converters have been recently used in many industrial applications, furthermore renewable energy such photovoltaic system technology can interface with a multilevel converter system in high, medium and low power application [2].A reduction of switching harmonics in the inverter output waveform without any unnecessary increase of the switching frequency of the converter is one of the important advantages of a multilevel converter [3].…”

This paper presents a multilevel power converter for non-standalone residential solar panel system. A single-phase three level photovoltaic inverter diode clamped multilevel inverter topology is designed and built to demonstrate the benefits and advantages of multilevel inverter in terms of output power quality. Pulse width modulations signal is generated using the microcontroller ATmega328 which generates pulse signals to control all the four switching devices of the inverter. To enable the photovoltaic inverter to be synchronized with the utility grid, a phase locked-loop is used. In addition, a closed loop feedback voltage control is designed to ensure the stability of the inverter input voltage so that the current and the voltage injected into the grid are sinusoidal and remain constant with rapid changes in the prevailing atmospheric conditions.
