As the present study, switching functions can be used to mimic a Four-Switch, Three-Phase Inverter (FSTPID) Brushless DC (BLDC) motor drive. The recommended representation shows the drive steady state and transient performance using inverter switching functions rather than actual circuits. The power conversion system, the BLDC motor, and the current and speed control system are all researched as part of the overall BLDC motor drive investigation. The tools Matlab/Simulink are used to implement the precise and approachable proposed model. This concept may be applied to demonstrate particular electrical variables, including phase current, line and phase voltages, diode and switch currents. Because issues occurred when two power switches were removed, direct phase current (DPC) control is utilized. Simulations and experimentation are used to verify the model that has been suggested.
