| Abstract |
This paper presents input PFC of SRM based variable
speed drive system. The four-phase SRM is fed from a singleswitch
per phase converter topology with an energy recovery
storage capacitor. Input PFC is achieved by a single-switch
boost converter which is ideal for appliance drives within the
power levels of 1kW and mostly operates from a single-phase
utility input. The proposed converter exhibits some advantages
like; single-switch per phase, common return point of phase
switches, snubberless operation, and four-quadrant operation
simply by changing phase firing sequence and position. A PWM
controller is used to generate the switching signals of the
appropriate phases according to the rotor position information.
A position sensing encoder is used to provide information to an
EPROM that is programmed to decide the firing sequence and
generates the appropriate firing signals. The principle of
operation is presented and the different modes of operation are
illustrated. Analytical derivations are carried out for each
identified mode of operation. Simulation and experimental
results have been provided to verify theoretical results. |
