Electrical power supply for electronic circuits arranged in a high voltage environment, which supply includes an isolating device interconnecting the low voltage side (secondary side) and the high voltage side (primary side) and including a primary side magnetic circuit (13a) coupled via a primary coil (14) to a power supply (12) of the electronic circuit in the high voltage environment, a secondary side magnetic circuit (13c) coupled via a secondary coil (15) to a low voltage side voltage source (10), and at least one intermediate magnetic circuit (13b) located between the primary and secondary magnetic circuits and coupled thereto via intermediate coils (16, 17) that include coil turn portions in the form of U-shaped conductors mounted to at least one circuit board (18, 19) that includes conducting tracks interconnecting the U-shaped conductors to close the turn portions of the intermediate coils.
