Development of four quadrant operation of DC to DC converter using single phase matrix converter

Abstract

<span>Single-Phase Matrix Converter (SPMC) is an advanced circuit topology that offer advantages such as the capability to regenerate energy back to the input, sinusoidal input and output current and a manageable input current displacement factor. By considering the opportunity of an advanced SPMC topology, further exploration on DC to DC operation is proposed. The four-quadrant operation of switching algorithm was developed to control the SPMC circuit. The voltage and current profile of each quadrant was investigated to validate the proposed switching control algorithm. As part of four quadrants DC to DC operation, the safe commutation switching algorithm was also developed in order to solve the commutation problem due to the used of an inductive load. The pulse width modulation (PWM) techniques was utilized to synthesize the output of the proposed converter. Results from MATLAB/Simulink are presented to validate the proposed circuit operation.</span>

Performance comparison of field oriented control based permanent magnet synchronous motor fed by matrix converter using PI and IP speed controllers

“…Matrix converters which directly connect the AC supply to an AC load are made up of bidirectional switches arranged in a matrix form. In a three phase in three-phase out matrix converter there are nine bidirectional switches arranged as a matrix [6][7][8][20][21][22]. By using various switching techniques, it is possible to generate output voltage waveforms with various frequencies and amplitudes to satisfy the load requirements.…”

“…One of the most attractive feature of matrix converters (MC) when compared to conventional voltage source inverter and active-rectifier combinations is the absence of a large DC link capacitance, since for high power applications this is a relatively expensive and bulky component which is widely recognized as having a significantly 1157 higher failure rate than other components. Hence, MCs are potentially attractive for aerospace applications, for example, for which reliability and weight are crucial [6][7][8], For example, by using Venturini's modulation technique in its simplified form, MCs are capable of providing simultaneous amplitude and frequency transformation of a three-phase voltage system and allow a wide range of output voltage, with desirable features, such as sinusoidal input and output waveforms, bi-directional energy flow capability, and with adjustable displacement angle (i.e. controllable input power factor) on the mains side under certain conditions [9][10], and high power/volume ratio.…”

“…A low pass filter can achieve that target. So in a MC-fed drive system, the input filter is usually included to meet the input power quality standard (to smooth the pulsed currents) to reduce input voltage distortion and to ensure the overall system stability [6,11]. A FOC-controlled PMSM drive provides better dynamic response and less torque ripples, and requires only a constant switching frequency.…”

Embedded processor system for controllable period-width multichannel pulse width modulation signals

“…A ratio based PWM technology in combination with proportional controller is adopted by [9] to achieve a smooth mid point potential controller. Generating PWM signal by comparing triangular wave with an adjustable direct current (DC) reference signal is performed by [10] to be used with D.C to D.C converter. Phase shift angle digital PWM (DPWM) for Phtovoltaic inverters is developed in [11], the proposed system is adapted to FPGAs platform.…”
