This paper corroborates three different hybrid modulation strategies suitable for single-phase voltage source inverter. The proposed method is formulated using fundamental switching and carrier based pulse width modulation methods.

Abstract  In this paper a new estimator for the measurement of the rms value of a noncoherent sampled sine-wave is proposed. The key feature of this estimator is that the sine-wave offset, a priori estimated, is removed from the sine-wave. A formula used to estimate the sinewave offset is also given in the paper. It has been proved by means of computer simulations and experimental results that...

This paper deals with the power quality (PQ) improvement by using a transformer less Hybrid Active Power Filter (HAPF) based on a six switch two leg inverter with battery and solar system through boost converter which increases the reliability of power supply by reducing the Total Harmonic Distortion (THD) and increase the voltage level. The control methods of instantaneous reactive power theor...

A new passive Power Factor Corrector (PFC) based on Valley Fill (VF) is proposed for an off-line Flyback converter. By adding an extra winding which is magnetically coupled to the Flyback transformer and electrically coupled to the VF, higher Power Factor (PF) and lower Total Harmonic Distortion (THD) can be achieved. The proposed circuit uses a high frequency inductor, low voltage capacitors t...

Abstract— Distributed energy resources systems are small power generation tools used to afford substitute solution or added enrichment of traditional electric power system. This paper is mainly concentrated on 1Ø multi-level inverter for Distributed Energy Resources. The objective of this paper is to reduce switches with increase in multi-level outputs which inherently reduces the cost & harmon...

With the vast development in the usage of Power electronic devices like Rectifiers (nonlinear loads) the current drawn from the line is distorted resulting in a High Total Harmonic Distortion (THD) and Low Power Factor (PF). Hence there is a continuous need for Power factor improvement and reduction of line current harmonics. The most popular topology for Active PFC is a boost converter as it d...

We analyze and present an input gain-varying scheme for maximizing dynamic range in a well-known Gm–C bandpass filter by both minimizing noise for small input signals, and by achieving balanced swing levels at all filter nodes for large input signals. A micropower bandpass filter suitable for use in cochlear implants and other powerconstrained biomedical applications was implemented and tested ...
