The invention is a power electronic system comprising at least one power electronic component implemented at least partly on at least one circuit board. The circuit boards are planar and circular or toroidal in shape with the center thereof comprising a circular opening having a diameter D cooperating with a hose for circulating a flow.

Flow-cooled toroidal or circular power electronics

The invention is an electronic power system () for energy conversion, comprising at least one electronic amplifier driver circuit (), at least one floating-ground isolated power supply () and at least one digital computation unit () for generating control signals (). The invention more specifically relates to a floating-ground isolated power supply () from control signals ().

Floating-ground isolated power supply for an electronic converter

The invention is a device () for cooling a power electronic system (EP) comprising at least one power electronic component () mounted on at least one circuit board (), the cooling device () comprises a hose () for circulating a flow () at an ambient temperature. The cooling device () comprises a first heat exchange surface () that is thermally connected to the power electronic components () and at least one second heat exchange surface (). The second heat exchange surface () is for heat exchange with the flow () circulating through the hose. The second heat exchange surface () is fitted inside the circulation hose () to remove heat by convection with the circulating flow (). The second heat exchange surface () is thermally connected to the first heat exchange surface ().
