<p>The system has a measuring input (ADC1) to measure a value of a supply voltage (U1) in relation to a reference potential (GND') at a ground input (ADC2). A test input (ADC3) is connected to a test voltage source and a positive terminal of a load via resistors, where the system determines a difference of electrical potentials of the test input and the ground input, determines a deviation of the difference of the electrical potentials, uses the deviation to correct the measured value of the supply voltage, and uses the corrected value of the supply voltage for controlling the power of the load. An independent claim is also included for a method for operating a system to control the power of a glow plug by pulse width modulation of a supply voltage.</p> |
