This paper targets the reduction of common-mode voltage in an indirect matrix converter (IMC) through an intelligent space-vector-based modulation technique. This mode of control results in lower dV/dt at the motor terminals, thereby, reducing voltage stress to windings; and reduced output voltage distortion resulting in lower machine losses. The conventional indirect space vector pulse-width modulation...
This paper discusses a modified indirect space vector pulse-width modulation (ISVPWM) technique for common mode voltage (CMV) reduction in a matrix converter (MC). The ISVPWM technique offers immense flexibility in making an intelligent choice of space vectors to not only achieve the objective of variable speed operation of the drive but also target other advanced features like reduced CMV and improved...
This paper discusses a modified space vector technique applied to an indirect matrix converter (IMC) which results in the reduction of common mode voltages and other advanced features. The conventional indirect space vector pulse-width modulation (SVPWM) method of controlling matrix converters involves the usage of two adjacent active vectors and one zero vector for both rectifying and inverting stages...
LCL filter is becoming an attractive choice over conventional L filters for grid-connected voltage source inverters (VSI) due to smaller inductor size and better attenuation of the ripple components in the grid current. The modulation of the VSI generates switched voltages which results in distorted currents. In this paper, a simple closed form analytical expression is derived for the higher order...
