New features and changes introduced in this version are described here:
A new block, Brushless DC Motor Drive, has been added to the Electric Drives/AC Drives library. It implements a brushless DC motor drive using a Permanent Magnet Synchronous Motor (PMSM) with trapezoidal back electromotive force (BEMF). It is possible to use a simplified version of the drive containing an average-value model of the inverter for faster simulation. In SimPowerSystems software, the Brushless DC Motor Drive block is commonly called the AC7 motor drive.
A new demo, Hybrid Electric Vehicle (HEV) Power Train (power_HEV_powertrain), shows a multi-domain simulation of a HEV power train based on SimPowerSystems and SimDriveline blocks. The HEV power train is of the series-parallel type, such as the one found in the Toyota Prius car. This HEV has two kinds of motive power sources, an electric motor and an internal combustion engine (ICE), in order to increase the drive train efficiency and reduce air pollution. It combines the advantages of the electric motor drive (no pollution and high available power at low speed) and the advantages of an internal combustion engine (high dynamic performances and low pollution at high speeds).
The automated conversion of old models, created with blocks from SimPowerSystems 2.3 or Power System Blockset™ 2 libraries, is no longer supported in Version 4.4 (R2007a).
The psbupdate function is obsolete as of Version 4.4 (R2007a).
