ABSTRACT:
In an inverter controller for a brushless DC motor, when the upper and lower pole power switching devices are sequentially operated, a commutating signal is applied so that a commutated power switching device is always turned on, and a pulse width modulated commutating signal is applied to the non-commutated power switching. device, and thereby a driving efficiency of the brushless DC motor can be effectively enhanced by reducing a delay time of a free-wheeling current at the turn off section of the pulse width modulated commutating signal and further, a thermal balance of the power switching devices can be realized by the uniform PWM control of the power switching devices connected to the upper and lower poles to gain an effect of uniformly distributing a thermal stress applied to a specific power switching device.
