Abstract

The present invention discloses a quick energy transfer circuit. The quick energy transfer circuit is connected between a first output end VO1 and a second output end VO2 of a switching power circuitwith multi-path output. The quick energy transfer circuit comprises a control unit, a first control switch Q13, a second control switch Q14 and an isolation unit; the second control switch Q14 is connected with the first output end VO1 and the second output end VO2 and is connected with the control unit; the first control switch Q13 is connected with the second switch Q14, and is connected with the control unit through the isolation unit; and the control unit is connected with the second output end VO2. The circuit achieves that energy of the first output end is transferred to or stops to be transferred to the second output end through opening and closing of the second control switch, the switch motion of the second control switch is controlled by the control unit, the quick energy transfer circuit is simple in structure, does not need extra transformers or voltage stabilizers, is low in cost, can achieve the voltage stabilization effect and avoids the load malfunction caused by too large load.

Description

technical field [0001] The invention relates to a fast energy transfer circuit and a power supply. Background technique [0002] For modern electronic systems, even for the simplest electronic system composed of a single-chip microcomputer and a single I / O interface circuit, its power supply voltage generally consists of multiple channels such as +5V, ±15V or ±12V, and For more complex electronic systems, different electronic systems not only have strict requirements on the above-mentioned various voltage combinations, but also have strict requirements on many electrical characteristics of these power supply voltages. For power supply users, they generally hope that the power supply products they choose are "fool-type", that is, as long as the selected power supply voltage does not exceed the maximum value of the power supply, no matter how the load characteristics of the system change, each The supply voltage remains accurate. However, most of the current multi-output pow...
