Abstract (en)

[origin: WO2022207571A1] This isolated voltage converter (106) comprises: - first and second global input terminals (P, N) intended to receive a global input voltage (VE) between them; and - a first and a second voltage conversion module (1081, 1082), each with a primary circuit and a secondary circuit that are isolated and connected by a magnetic circuit, the primary circuits being connected in series between the global input terminals (P, N) so as each to receive only a portion of the global input voltage (VE) as local input voltage (VE1, VE2). It furthermore comprises a device (118) for regulating the local input voltages (VE1, VE2) so as to keep them in a predefined ratio, for example to keep equal to one another.
