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 ...

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 ...

Light scattering at nano-textured surfaces in thin film silicon solar cells

Christophe Ballif, Franz-Josef Haug, Corsin Battaglia

State-of-the-art solar cells based on thin film silicon make use of random textures for absorption enhancement; in the past, the development of these textures was carried out empirically, and in most applications this is still the case. Attempts to underst ...

A four-motor drive supplied from a triple three-phase voltage source inverter

Drazen Dujic

Since control of a three-phase machine requires only two currents, it is possible to independently control a number of three-phase machines using reduced-switch-count voltage source inverter (VSI) topologies. One such configuration consists of n three-phas ...
