Abstract: A power supply circuit may include at least a first and a second current generator. Each current generator is implemented with an electronic converter comprising a switching stage, a current sensor generating a feedback signal, and a regulator circuit configured to drive the switching stage as a function of the feedback signal. Specifically, each current sensor is a low-side current sensor configured to generate a feedback signal indicative of the current received via the negative terminal of the respective current generator. The power supply circuit may include also include a control circuit configured for various tasks pertaining to the first and second generators.

Abstract: A method of operating an electrical power supply device having a primary side and a secondary side is provided. The method includes transmitting with an optocoupler arranged between the primary side and the secondary side a wide band control signal and a numerical information signal. The method further includes transmitting the control signal and the information signal over a rectangular-wave signal modulated in combination with frequency modulation and pulse width modulation. The control signal and the information signal are the modulating signals for frequency modulation and pulse width modulation of said rectangular-wave signal.
