Abstract—There has been an increasing interest in the development
of energy-efficient appliances using renewable energy
sources. This paper deals with a Photovoltaic (PV) powered
BLDC drive as a sustainable solution to air conditioning compressor
drive. Compressor of an air conditioner (AC) accounts
for 95% of its total power consumption. The bottle necks of
operating a compressor drive on PV are: supplying high starting
current, effect of intermittent nature of PV on drive performace,
effective power management and stable operation in standalone
mode. In this work, a control algorithm is proposed to operate
a BLDC drive on PV and and a hybrid energy storage system
(HESS). HESS is employed to smoothen the intermittent nature
of PV and a HESS SOC control algorithm is formulated. The
control algorithm limits the drive starting/transient current to 1.5
times the rated current. A virtual damping of DC link voltage
is employed to make the system stable. The simulation results
confirm the efficacy of control algorithm to obtain desired drive
performance under various disturbances in PV and HESS.
