In this paper space vector model of a fifteen-phase voltage source inverter (VSI) is presented. The space vector Pulse Width Modulation (SVPWM) of a fifteen-phase voltage source inverter (VSI) with the aim of producing sinusoidal output waveform, is illustrated. Generalized space vector theory is used to model the inverter and the SVPWM. As per the general inverter switching theory there are 215 =...
Multiphase drives are now becoming serious competitor to traditional three-phase drives due to reasons of better fault tolerant property and reduced per-phase converter rating that are especially suited to high power drives application. One of the major factor of widespread research on multiphase drive are the availability of high computational power of control platforms such as DSP and FPGAs. With...
The paper proposes a computationally efficient finite state model based current control of a three-level neutral point clamped (NPC) five-phase voltage source inverter. The space vector model of a five-phase voltage source inverter (VSI) yields 243 space vectors, with 240 active and three zero vectors. The presented technique utilizes a modified switching algorithm to reduce the computation time while...
In this paper comprehensive space vector model of a thirteen-phase voltage source inverter (VSI) is reported. The paper also discusses the space vector Pulse Width Modulation (SVPWM) of a thirteen-phase voltage source inverter (VSI) with the aim of producing sinusoidal output waveform. Generalized space vector theory is used to achieve the SVPWM. As per the general inverter switching theory there...
In this paper a generalized multi-phase space vector theory is considered for developing the space vector modulation of a three-phase to seven-phase direct matrix converter (DMC). The modulation is based on the control of the voltage vectors in the first d-q plane, while imposing the remaining voltage vectors in the second and the third planes (x1–y1, x2–y2) zero. The duty cycles of the bidirectional...
In this paper comprehensive space vector model of an eleven-phase voltage source inverter (VSI). is presented. The total numbers of switching combinations that give 211 = 2048 space vectors are elaborated out of which 2046 are active and 2 are zero vectors. The space vectors thus obtained are then transformed into five planes (one is d-q and rest are x-y). The complete mapping of space vectors are...
Multi-phase (more than three-phase) converters are required mainly for feeding variable speed multi-phase drive systems. This paper presents one such solution by using direct ac-ac converter that can be used to supply a seven-phase drive system. Simple Pulse width modulation (PWM) technique is developed for the proposed matrix converter configuration. The developed modulation technique is based on...
