Abstract
A method and a circuit for complying with specified maximum values for output parameters a power supply unit includes at least a non-floating switch converter, an output voltage control unit, a current limiter and a switch element, wherein actual values of the current and voltage outputs of the power supply unit are measured continuously, where an evaluation unit calculates actual output power values of the power supply unit from the actual measured values of the output current and voltages, and subsequently compares at least the respective actually measured values of the output current and the respective actually calculated output power values with specified maximum values such that if at least one of the specified maximum values is exceeded by an actually measured value of the output current and/or by an actually calculated output power value, a current flow in the power supply unit is then interrupted by the evaluation unit.
