<p>A method is for protecting a DC generator against overvoltage in the event of a loss of load. A voltage limit value is defined and, when starting the current generator, one or a few small current pulses are generated during an initial phase. The voltage is measured across the output of the current generator during the initial phase and the voltages measured across the output of the current generator are compared with the voltage limit value. There is a changeover to normal operation only if all the voltages across the output of the current generator measured during the initial phase are below the voltage limit value. The current generation is interrupted and a loss of load is indicated if any one of the voltages across the output of the current generator measured during the initial phase exceeds the voltage limit value.</p> |
