  • Activation apparatus and method for activating a direct voltage converter
    Patent number: 9467059
    Abstract: The invention relates to an activation apparatus (20) for a galvanically decoupled direct voltage converter having a synchronous rectifier, comprising a signal generating device (22), which is designed to generate control signals (22c, 22d) for switch devices of the synchronous rectifier and a reference current signal (22b), a first comparator device (23), which is coupled to the signal generating device (22), and which is designed to detect the secondary-side output current (Jo) of the synchronous rectifier, compare it to the reference current signal (22b) and generate a current control signal in dependence on the comparison, and a pulse width modulation device (25), which is coupled to the signal generating device (22) and the first comparator device (23) and which is designed to generate pulse width modulated activation signals (25a) for the switch devices of the synchronous rectifier on the basis of the control signals (22c, 22d) and the current control signal, wherein the signal generating device (22) is
