A power supply receives AC power and generates a DC output voltage. The power supply may be divided into a primary section that converts AC power to a relatively high DC voltage. A secondary section converts this relatively high DC voltage into a well-regulated lower DC voltage. In an embodiment, the current and/or power supplied by the primary to the secondary side is used by the secondary side in a closed-loop feedback system to limit the current drawn by the secondary side to a configurable value.

A system for automatically addressing serially connected slave devices includes a master device and multiple slave devices each including a serial communication transceiver, an address input port, an address output port, and a controller. The system also includes a serial communication wiring bus connected between the serial communication transceivers of the master and slave devices, and at least one digital address line connected between the address input ports and the address output ports. Each controller is configured to receive a PWM or PFM signal from a previous one of the multiple slave devices, determine an address for the slave device including the controller according to the received PWM or PFM signal, and transmit a PWM or PFM signal indicative of the determined address to a subsequent one of the multiple slave devices.

A control circuit for controlling multiple power supplies having their outputs coupled in series is configured to in response to an output current reaching a defined current threshold of a power supply of the power supplies, control the power supply to operate in its constant current mode so that the output current is regulated at the defined current threshold as the remaining power supplies operate in their constant voltage mode, and in response to the output voltage of the power supply reaching a defined voltage threshold, control the power supply to operate in its constant voltage mode so that the power supply provides a first regulated output voltage to its output as the remaining power supplies provide a second regulated output voltage different than the first regulated output voltage to their output. Various other systems, power supplies, control circuit and methods are also disclosed.
