Abstract: The present invention relates to Electronic Control Units (ECUs) for use in ring-like power distribution architectures as well as to ring-like power distribution architectures comprising such ECUs. It also relates to vehicles comprising such ring-like power distribution architectures. In an aspect, an ECU comprises a first ECU terminal for receiving power from a first power source (PS) terminal of a first power source, means for determining whether current is flowing into the first ECU terminal or out of the first ECU terminal, and means for adjusting a sensitivity of a first ECU fuse associated with the first ECU terminal based on whether current is flowing into the first ECU terminal or out of the first ECU terminal.

Abstract: An electronic device for series connection on a power supply line, wherein the device comprises a plurality of switches comprising at least a first switch, a second switch, and a third switch. The device further comprises a control unit configured to perform the following steps: operating error detection means during operation of the device in a first mode; operating the device in a second mode in response to an erroneous power state being detected by the error detection means during operation of the device in the first mode; operating the error detection means during operation of the device in the second mode in order to determine an error location associated with the erroneous power state detected by the error detection means during operation of the device in the first mode.

Abstract: A balancing system for balancing respective voltages of N consecutively connected capacitors during charging or discharging includes balancing units, each having a pair of associated switches and an electromagnetic coil. An inter-switch junction is connected to an inter-capacitor junction of a corresponding group of capacitors through the electromagnetic coil. A control and generation circuit generates PWM control signals and transmits a generated PWM control signal to each of the switches. The PWM control signals have fixed duty cycles that do not vary temporarily during charging or discharging of the N capacitors. The duty cycles of two PWM control signals transmitted to two associated switches are complementary for each balancing unit.
