Abstract:
A power supply device including a diode bridge, a converter module, and an inrush control module. The diode bridge is configured to rectify an input voltage. The converter module is coupled to the diode bridge and is configured to convert the input voltage into a direct current regulated output voltage. The inrush control module is connected to the diode bridge and is configured to gradually activate a transistor and to limit an inrush current peak value based upon a zero crossing being detected in the input voltage. A method for limiting the inrush current peak value is also disclosed.
