Short-circuit protection in dual voltage electrical system fitted to motor vehicle, uses detection of short circuit to deactivate DC/DC converter and to open switch that connects earth circuits for high and low voltage supplies |
摘要 |
The short-circuit protection detects the presence of a short circuit between high and low voltage supply circuits, then deactivates the DC/DC converter (4) and separates, using a power relay switch (8), the earth circuits (C and D) for the low and high voltage circuits respectively. The vehicle driver is then informed by a signaling device or message.
