Self -adaptation circuit that flow equalizes

The utility model relates to a self -adaptation circuit that flow equalizes, including a plurality of high -frequency transformer T and the first diode D1 the same with high -frequency transformer quantity, a plurality of high -frequency transformer T's primary establishes ties in order, and the idle both ends IN1 of high -frequency transformer primary, IN2 is connected to external power source, every high -frequency transformer T secondary coil's one end and the anodal of a first diode D1 are connected, every first diode D1's negative pole common connecting, and its common port with be not connected with ground through external load R, every high -frequency transformer T secondary coil's other end difference ground connection. The utility model discloses a circuit that flow equalizes, when solving the transformer under unified use of a plurality of the same parameters, the unbalanced problem of current distribution, the change that can adapt to the load automatically comes the operating current on the average allocation diode. An underloading can not appear, another serious overstrain phenomenon. The efficiency of whole circuit is improved, reduce the reactive loss of whole circuit, guaranteed reliability, the stability of circuit.
