Investigation of Power Factor on Harmonic Effect due to Types of Volatge Source

Abstract

This paper discussed about power factor on harmonic effect due to types of voltage source. Usually, the voltage source is sinusoidal, But in actually, the condition of the load is has voltage sources through the elements where the output voltage of element as input to load is did not pure sinusoidal, Joy example at POC between transformer and linear load and nonlinear load The research has done with Schhafher Power Quality Analyzer. The research was focused to power factor (of), THD and harmonic energy losses cost from measurement where load is induction motor and ASD. As voltage source in this research are sing wave and combinations of 3rd, 5th and 7th harmonic order Mie harmonic 313, and harmonic 337. This paper presents the development of a simple 5-level multilevel inverter for low power applications that mot exceeding 30W using the common LM350 voltage regulator IC. A microcontroller with dedicated program is used to control on the biasing resistance of the IC and H- bridge inverter in order to produce the quasi-sinewave looking waveform. Analysis of the output results are shown with levels of percentage harmonics. The development of this multilevel inverter serves as a new concept of study for multilevel inverters considering its simplicity and low cost.
