Dc bus utilisation in multiphase VSI supplied drives with a composite stator phase number

Drazen Dujic

Multiphase variable-speed drives are typically supplied from a two-level voltage source inverter (VSI). The number of phases of the machine and hence the legs of the inverter can be either a prime or a composite number. Limits of the dc bus utilisation in ...

Harmonic distortion factor of space vector PWM for a five-phase inverter

Drazen Dujic

Various PWM methods for multi-phase (n>3) two-level voltage source inverters (VSIs) have been developed recently. Relatively little work has however been done in relation to switching harmonic properties of these PWM methods and their impact on current rip ...

Current ripple in inverter-fed five-phase drives with space-vector PWM

Drazen Dujic

A number of PWM techniques have been developed in recent times for five-phase voltage source inverters (VSIs), which enable sinusoidal output voltage generation. Relatively little attention has been however paid to the current ripple caused by these PWM me ...

Design methodology and comparison of rectifiers for UHF-band RFIDs

Catherine Dehollain, Francesco Mazzilli, Norbert Jöhl

Rectifiers are important energy converters and henceforth crucial building blocks for RFID applications. In the first half of the work, we have presented a design methodology for matching the rectifier input impedance with the antenna to maximize the recti ...

A vector controlled single-phase voltage source inverter with enhanced dynamic response

Alfred Rufer

Vector (dq) control is a powerful technique used in high dynamic performance inverters. The transformation of ac into dc quantities allows the controller to be designed as for dc-dc converters, with infinite gain at the steady-state operating point for zer ...

Dead-Time Effects in Voltage Source Inverter Fed Multi-Phase AC Motor Drives and Their Compensation

Drazen Dujic

Inverter dead-time effects have been investigated in detail in the past for three-phase drives supplied from a three-phase voltage source inverter (VSI). A similar study has never been conducted in conjunction with multi-phase (more than three phases) driv ...

The Impact of inverter dead time on performance of n-motor drives supplied from (2n+1)-leg VSI

Drazen Dujic

Industrial applications often require two or more variable-speed electric drives, which have to be controlled independently. Over the past decade research efforts have been made to reduce the number of power electronic devices required in multi-motor drive ...
