DESIGN AND ANALYSIS OF A WIND POWER ENERGY CONVERSION SYSTEMS WITH TWO-PHASE PM MACHINE AND A RECTIFIER WITH REDUCED NUMBER OF CONTROLLED SWITCHES

Abstract

Switching losses and power
efficiency are both improved by using multilevel
inverters that decrease voltage distortions
during switching operations. When it comes to
power efficiency, reduced switching harmonics,
and a smaller filter inductor than traditional
half-bridge and full-bridge inverters, the
multilayer inverter is the clear winner. A
rectifier with a modest number of controlled
switches is connected to a two-phase
permanent magnet (PM) synchronous machine
in this project. It is possible to utilise them in
grid-connected applications, stand-alone
applications, or to feed a microgrid.
While certain three-phase generating systems
with fewer controlled switches may provide
sinusoidally regulated machine currents, the
suggested topologies can also lower the dc-link
voltage and provide low harmonic distortion for
dq currents, making them more efficient. It has
a single controlled switch, is easy to construct
and manage, and has minimal harmonic
distortion and a good power factor throughout
the whole system. Extensive MATLAB/Simulink
simulation studies are used to assess the power
generating system's performance.
Pulsewidth modulated power converters and
synchronous generators are included in the
index terms for AC machines, power
conversion, and power electronics.
