常见的电子调压器是通过控制双极性大功率管的接通或关断发电机激磁回路方式来调节激磁电流,从而达到自动稳定发电机端电压的目的。然而,在使用中经常导致大功率管损坏的主要原因不外乎以下三种,一是晶体管在换向瞬间(例缸由导通到截止
Common electronic voltage regulator is through the control of bipolar power tube on or off the excitation circuit of the generator to adjust the excitation current, so as to achieve the purpose of automatically stabilizing the generator terminal voltage. However, the main reason that often causes the high-power tube to damage in use is nothing more than the following three kinds, one is that the transistor is changed to the moment
