Abstract (en)
[origin: EP0692757A2] A number of different regulated voltages (Ual-Uan) are provided by a d.c. voltage converter (1) that are in the form of a switched power supply. A first regulating stage (8) compares one output (11) with a reference value and applies a correcting action to a pulse width modulator (17) controlling the converter. The other regulating stages operate on the remaining voltage outputs and corrections are applied in sequence to adjust the controls of the pulse width modulator. <IMAGE>
