New research has categorized all existing fault detection and localization strategies for grid-connected PV inverters. The overview also provides a classification of various component failure modes ...

Case study examines a common PV inverter failure that can drive uncommon issues in the field — namely, damage to the AC protection equipment from DC fault currents for short periods during transformer ...

Lucid Motors is recalling 2,039 Air Pure electric sedans because they may lose power while driving due to a damaged inverter.

A team of scientists in the United States has combined both spatial and temporal attention mechanisms to develop a new approach for PV inverter fault detection. Training the new method on a dataset ...

The new IEC standard 63027 will eliminate some of the weaknesses of the old UL 1699B standard, which did not simulate real operation sufficiently. Image: Fraunhofer ISE German research body Fraunhofer ...

Kehua has announced that its SPI series 1500V/350kW string inverter has passed High Voltage Ride Through (HVRT) and Low (zero) Voltage Ride Through (LVRT) testing. Requirements for HVRT and LVRT ...

The TIDA-00442 TI design provides a reference solution for detecting ground faults in inverter based drives. Inverter current is measured on both dc-positive and dc-negative buses using shunt ...

2011 NEC Section 690.11 requires detection and interruption of “arcing faults resulting from a failure in the intended continuity of a conductor, connection, module, or other system component.” This ...

The Chrysler Group announced that 4,141 electric Cinquecentos may suffer from power loss or even short circuit due to a design flaw in the PIM. This is the second time the Stateside-only Fiat 500e has ...
