This paper proposes a novel Bridgeless converter to drive and speed control of PMBLDC motor. PMBLDC motor possess high torque/weight ratio, operate at high speed, very compact and are electronically controlled. The speed control of BLDC motor is achieved by controlling the DC link voltage of the voltage source inverter feeding BLDC motor using a single voltage sensor. Conventional bridged topology is replaced by bridgeless topology. Conventional PMBLDCM drive consists of a VSI and a PMBLDC motor powered by a diode bridge rectifier, fed by single-phase AC mains and a smoothening DC capacitor. Due mainly to uncontrolled charging of the DC capacitor at the input AC mains, there will be resultant problems, such as a poor power factor, and increased THD of current. Therefore, it has become necessary to design a suitable passive filter to reduce THD, and improve the power factor of a PMBLDC motor drive. Performance at various operating conditions such as starting, dynamic and steady state behavior are analyzed and suitability of the proposed system is demonstrated using MATLAB/Simulink based simulation results.
