Abstract: A control circuit for a first switch includes at least one transistor, the first switch being arranged in series with a second switch in an inverter arm of an electrical power supply device supplying a load connected to the mid-point of the series arrangement of the first and second switch. The control circuit is configured to adjust the gate-source voltage of the at least one transistor of the first switch according to a control scheme including, during a deactivation period of the first switch, the increase of the gate-source voltage in a time window including the deactivation of the second switch and the reduction of the gate-source voltage in a time window including the activation of the second switch.

Abstract: Electrical power supply circuit for a power module comprising an electrical transformer, a first substrate having a first side including a heat sink and a second side, a second substrate having a first side including a heat sink and a second side, first metal tracks disposed on the second side of the first substrate, second metal tracks disposed on the second side of the second substrate, electrical connectors disposed between the first and second substrates to electrically connect a first metal track to a second metal track, the primary circuit of the electrical transformer comprising a first part of the first metal tracks and a first part of the second metal tracks, and the secondary circuit of the electrical transformer comprising a second part of the first metal tracks and a second part of the second metal tracks.

Abstract: A power conversion system for an aircraft on-board power system converts high voltage DC to low voltage DC and vice versa. The system includes switching means configured so that the system operates in a plurality of configurations, each forming an isolated DC/DC converter.
