Abstract
The invention pertains to a bridge circuit and a drive circuit for it, in particular for driving a brushless DC motor. The bridge circuit exclusively consists of n-channel field-effect transistors. An auxiliary potential generated by at least one potential sliding capacitor is provided for driving these particular field-effect transistors which are connected to the positive supply voltage. The auxiliary potential is already built up before the starting of the motor by means of special switching measures, and said auxiliary potential exists at a defined intensity during extended standstill times of the motor.
