In the document entitled “New Gate Control Unit for Automotive Synchronous Rectifiers”, authors Stephan Rees and Ulrich Ammann, published by the Institute of Power Electronics and Control Engineering, University of Stuttgart, there is shown a control device for suitably controlling the transistors of the bridge rectifier in order to correctly rectify the sinusoidal induced current.
A control device is connected to each transistor of the bridge rectifier/inverter. The control device comprises an operational amplifier for controlling the associated transistor.
One of the drawbacks of this device is that it is subjected to the leakage currents coming from the battery.
Because of this, the transistors of the bridge rectifier/inverter may be damaged because of these leakage currents and, when the vehicle is stopped, the bridge rectifier/inverter continuously consumes current, which may discharge the battery.
