This paper presents a novel unity power factor bidirectional battery charger using single-phase matrix converter (SPMC). The advantages of the proposed converter are its capability to perform bidirectional operation for charging and discharging purposes hence low harmonic distortion in supply current and nearly unity power factor over a wide operating output power range. Its circuit has employed only...
This paper presents the performance comparison between Hysteresis Current Control and Proportional Integral control techniques, used in Current Control Loop as a power factor correction for AC-DC converter using single phase matrix converter-fed permanent magnet DC motor. Conventional controlled rectifier often incurs non-sinusoidal supply current waveform with high harmonics content, which contributes...
In this paper, a computer simulation model of Hysteresis Current Control (HCC) technique for AC to DC converter fed permanent magnet DC motor (PMDC) using single-phase matrix converter (SPMC) topology is investigated. As the AC-DC converter fed PMDC motor yields a non-linear load, this can affect the generating of harmonics resulting high total harmonics distortion (THD) level hence low power factor...
An optimization model of the input current for a variable input voltage in CMOS AC/DC converter is proposed in order to achieve regulation control of an AC/DC converter. An input current model of CMOS converter is obtained by applying an average method in converter circuit over one's switching period. This model is implemented in Pspice circuit simulation tool to verify an averaged model of the input...

In this paper, simulation of safe commutation switching sequence for an AC-DC single-phase matrix converter (SPMC) with combination of conventional LC filter and damping resistor were proposed. SPMC used the multiple PWM technique as its basic switching operation for synthesizing the required output. The switching sequence was developed in order to provide a continuous path for current flow due to...

This paper presents Single-Phase Matrix Converter (SPMC) with reduced switch count operating as buck or boost rectifier. Instead of eight switches, SPMC with reduced switch count employed six switches due to redundant switches that present in previous buck and boost rectifiers using SPMC. Both buck and boost rectifiers are using the same proposed circuit topology which only six switches are being...

The NARX identification process is performed in two steps, namely model structure selection and parameter estimation. Structure selection involves selecting a subset of regressors to use that best describes the system. The structure selection task is a critical part of the system identification process as the number of candidate structures grows exponentially with higher lag spaces. A Binary Particle...
This paper presents a Single Phase Matrix Converter (SPMC) operated as an AC-DC controlled rectifier driving the non-linear load (constant power load).
