To reduce the wave of the output, the input terminal of the circuit is using full-wave double rectifier, the output wave is reduced by increasing the AC voltage. The practice proves it can get good results. With ordinary methods, the 60V AC is rectified, if we want to get the same low output wave, at least 5 470u/160v capacitors can filter the wave. The parameters are as follows: input AC voltage is 35-70V, output DC voltage is 24V, output DC current is 0.65A, output wave (full load) is ≤15mV(Vp-p).
