Space Vector Modulation of a Seven-Phase Voltage Source Inverter

, 2006
A generalized multi-phase space vector theory is considered for developing the space vector modulation of a seven-phase voltage source inverter. The modulation is based on the control of the voltage vector in the first d-q plane, imposing to be zero the ...

Iteratively Decoded Variable Length Space-Time Coded Modulation: Code Construction and Convergence Analysis

, 2007
An Iteratively Decoded Variable Length Space Time Coded Modulation (VL-STCM-ID) scheme capable of simultaneously providing both coding and iteration gain as well as multiplexing and diversity gain is proposed. Non-binary unity-rate precoders are employed

Space-Vector-Based Hybrid Pulsewidth Modulation Techniques for Reduced Harmonic Distortion and Switching Loss

, 2010
Novel switching sequences can be employed in spacevector-based pulsewidth modulation (PWM) of voltage source inverters. Differentswitching sequences are evaluated and compared in terms of inverter switching loss.

A Bit-Stream based space vector modulator

, 2010
Bit-Stream based control, which uses one bit wide signals to control power electronics applications, is a new approach for controller design in power electronic systems. Bit-Stream signals are inherently high frequency in nature, and as such some form of

Direct Power Control Strategy based on Space Vector Modulation

Kongzhi Yu Xinxi Jishu, 2010
Direct power control technology is applied on three-phase PWM rectifier. Using space vector modulation instead of switching tables can eliminate the bad effect of unconstant switching frequency on the rectifier.

Space Vector Modulation Technique to Reduce Leakage Current of a Transformerless Three-Phase Four-Leg Photovoltaic System

Iranian Journal of Electrical and Electronic Engineering, 2017
Photovoltaic systems integrated to the grid have received considerable attention around the world. They can be connected to the electrical grid via galvanic isolation (transformer) or without it (transformerless).

Space-Time Trellis and Space-Time Block Coding Versus Adaptive Modulation and Coding Aided OFDM for Wideband Channels

, 2006
—The achievable performance of channel coded spacetime trellis (STT) codes and space-time block (STB) codes transmitted over wideband channels is studied in the context of schemes having an effective throughput of 2 bits/symbol (BPS) and 3 BPS.

Space-Time-Frequency Shift Keying for Dispersive Channels

, 2011
Inspired by the concept of the Space-Time Shift Keying (STSK) modulation, in this paper we proposed the Space-Frequency Shift Keying (SFSK) modulation as well as the Space-Time-Frequency Shift Keying (STFSK) concept which spreads the transmit signal not ...
