Fuel cell electrical converter for motor vehicle e.g. car, has control unit delivering control signal to voltage clipper so that under influence of signal average voltage at input of current inverter is lowered to threshold voltage

摘要

The converter has a control unit (6) delivering a control signal to a voltage lowering clipper (1) so that under the influence of the signal an average voltage at an input of current inverter is lowered to a threshold voltage V sin activation zone. The voltage is maintained equal to that of the cell voltage V pin resistance zone. The output of the converter is limited when output current of inverter (2) reaches a value I max. The current inverters (2) output is controlled so that the value of the peak voltage delivered by the inverter is equal to V s.
