Patent ID: 8837171

Claim:
A method for operating a DC/DC converter circuit configuration, the DC/DC converter circuit configuration having a rectifier configuration, an inductance and at least one circuit breaker for switching the inductance on an input side, which comprises the steps of: variably changing an off time of the circuit breaker on a basis of an output power of the DC/DC converter circuit configuration; respectively switching the circuit breaker on in a region of a minimum of a voltage curve across the circuit breaker; determining a switch-on time of the circuit breaker as a point of intersection between a monotonously increasing ramp voltage curve and a modified feedback voltage curve; producing the modified feedback voltage curve by adding the voltage curve across the circuit breaker to an averaged feedback voltage; and determining the averaged feedback voltage by averaging a difference between an output voltage of the DC/DC converter circuit configuration and a desired value of the output voltage of the DC/DC converter circuit configuration.
