A bobbin used in a transformer is disclosed. The bobbin includes a main body, two side walls, two wire collecting bases and at least one extension wire collecting base. The main body has a tunnel. The two side walls are disposed on the two ends of the main body, respectively. The tunnel passes through the two ends of the main body and the two side walls. The two wire collecting bases are disposed on the two side walls respectively or on one of the two side walls. Each wire collecting base has at least one wire collecting part. The extension wire collecting base has at least one extension wire collecting part. The extension wire collecting base can couple with the wire collecting base.

Bobbin and transformer comprising the same

A multi-output buck converting apparatus with a controllable energy-releasing function includes a main buck converter and at least one auxiliary buck converter to provide multi-output voltages. The multi-output buck converting apparatus further includes an energy releasing unit and an abnormal voltage signal generating unit. The abnormal voltage signal generating unit generates a control signal to control a switch device of the energy releasing unit when the multi-output buck converting apparatus shuts down. Therefore, the energy, which is stored in the auxiliary buck converter, can be released through the energy releasing unit so as to avoid returning the energy to the main buck converter and rebounding a main output voltage.

Multi-output buck converting apparatus with controllable energy-releasing function

A multi-output buck converting apparatus with a shutdown protection includes a main buck converter and at least one auxiliary buck converter to provide multi-output voltages. The multi-output buck converting apparatus further includes an abnormal voltage signal generating unit. The abnormal voltage signal generating unit generates a control signal to control switch devices of the auxiliary buck converter when the multi-output buck converting apparatus shuts down. Therefore, the stored energy in the auxiliary buck converter can be released through internal loops or external loops with connected operational loads so as to avoid the recovering energy rebounding a main output voltage of the main buck converter.
