发明名称 Method and system for detecting a defect on the DC power supply bus of a power converter
摘要 <p>The method involves determining a mean value (V) of a voltage (Vbus) of a direct current (DC) power supply bus, and determining the ripple (VppH1) of the voltage of the DC power supply bus. A variation of the mean value with respect to the ripple is monitored, and a defect on the DC power supply bus is determined as a function of the rate of the variation, where the defect consists of an anomaly on an inductor (L1) of the DC power supply bus, a power overload of a power converter, or advanced wear of a bus capacitor (Cbus). An independent claim is also included for a system for detecting a defect on a DC power supply bus of a power converter connected to an electrical distribution network.</p>
