%X The major function of this
proposed research is to control the speed of the brushless DC motor with sensor
less control for four-switch three phase inverter. This proposed system is
simplified the topological structure of the conventional six-switch three phase
inverter. In this proposed method, a new structure of four-switch three phase
inverter</span><span class=\"apple-converted-space\" style=\"font-size:12px;font-family:Verdana;\"><span lang=\"EN-US\" style=\"font-size:12px;font-family:Verdana;\">&nbsp;</span></span><span lang=\"EN-US\" style=\"font-size:10pt;font-family:'color:#31849B;\"></span><span style=\"font-size:12px;font-family:Verdana;\">[1]</span><span class=\"apple-converted-space\"></span><span lang=\"EN-US\" style=\"font-size:12px;font-family:Verdana;\">&nbsp;</span><span lang=\"EN-US\" style=\"font-size:10pt;font-family:'}', serif;\"><span style=\"font-size:12px;font-family:Verdana;\">with reduced number of switches for system is introduced to

four-switch three phase inverter reduction of switches, low cost control and
saving of hall sensor were incorporated. The feasibility of the proposed sensor
less control four-switch three phase inverter fed brushless DC motor drive is
implemented, analysed using MATLAB/SIMULINK, effective simulation results have
been validated out successfully.
