초록
In this paper, the voltage control is applied to the adjustable speed operation of BLDC motor with the trapezoidal back emf waveform. Torque chrateristics of BLDC are investigated through Fourier analysis when the pulse width modulation inverter is applied. Also, this paper consisders the theoretical problem of eliminating some harmonic components in inverter output waveforms, which, in turn, allows to remove some ripple components. Numerical technique is applied to solve the transcendental equations of the problem by the computer.
