Abstract

This invention relates to control device about one equal drive power supplier, which comprises one feedback control circuit to supply power and flexible input end is used to set flexible start time of power supplier with first and second output ends are used to output first and second signals to couple power supplier one first switch and second switch to control power supplier output with one protection unit composed of voltage input end, current detection end and power detection end and signal detection end.

Description

technical field [0001] The invention relates to a control device of a power supply, in particular to a control device of an proportional driving power supply. Background technique [0002] The advantage of the proportional driving power supply circuit is high efficiency, especially when driving a bipolar transistor, its control device does not need to generate a large base current to drive the bipolar transistor. The control device only needs to generate a small control signal to drive and control a high-watt power output. [0003] Figure 1 is a circuit of a ratio-driven power supply. A first output signal S generated by the control device (not shown in the figure) 1 and a second output signal S 2 , are used to control the driving transistors 51 and 61 respectively. The driving transistors 51 and 61 are connected to a driving transformer 20 to control switching of the power transistors 50 and 60 . The power transistors 50 , 60 and the capacitors 40 , 45 form a half-brid...
