Matrix Converter Using Direct Svm Method with Input Power Factor Compensation

Matrix Converter Using Direct Svm Method with Input Power Factor Compensation

The matrix converter (MC) for motor drive applications and energy conversion systems is steadily increasing due to its main advantage of performing a direct coupling between two three-phase alternating current sources without the need of an intermediate direct current bus. The input filters characteristics design for matrix converter system: to reduce the high harmonic components at the main po...

Space Vector Modulation for an Indirect Matrix Converter with Improved Input Power Factor

Pulse width modulation strategies have been developed for indirect matrix converters (IMCs) in order to improve their performance. In indirect matrix converters, the LC input filter is used to remove input current harmonics and electromagnetic interference problems. Unfortunately, due to the existence of the input filter, the input power factor is diminished, especially during operation at low ...

Advanced Direct Power Control Method of UPFC by Using Matrix Converter

This paper presents a direct power control (DPC) for three-phase matrix converters operating as unified power flow controllers (UPFCs). Matrix converters (MCs) allow the direct ac/ac power conversion without dc energy storage links; therefore, the MC-based UPFC (MCUPFC) has reduced volume and cost, reduced capacitor power losses, together with higher reliability. Theoretical principles of direc...

Input Power Factor Control of Matrix Converter Based Transmitter for Transient Electromagnetic Sounding

Three-phase to single-phase matrix converter (TSMC) is used as the transmitter for transient electromagnetic method (TEM) instrument, instead of an AC-DC converter and an H-bridge inverter. The transmitter produces excitation current for primary field. The output current has a waveform with a bipolar square of half duty cycle, which is required by TEM. The space vector PWM based on input curren...
