IPM module
IPM module is integrated with 3 pair
complementary IGBT tube, whose
connection and disconnection are
controlled through PWM so that
DC bus voltage is imposed to the
winding of compressor. The magnetic
eld will enable the rotor to rotate
for running of the compressor.
PFC module
IPM module is integrated with 4
LED an 2 MOS tubes. The AC power
is converted into DC power and
theconnection and disconnection of
MOS tube are controlled through
PWM so that voltage is increased,
