SEMICONDUCTOR SWITCHING CIRCUITS FOR SRM (POWER CONTROLLERS)
The selection of controller (converter) depends
upon the application. One of the main aspects of the research in SRM drives has
been the converter design. The main objectives of the design of the converter
are performance of the drive and cost of the drive.
The power semiconductor switching circuits used are
1.
Two power
semiconductor switching devices per phase and two diodes.
2.
(n+1)
power semiconductor switching devices (n+1) diodes.
3.
Phase
winding using bifilar wires.
4.
Split-link
circuit used with even-phase number.
5.
C-dump
circuit.
