Abstract

The utility model provides a capacitor transformer. The capacitor transformer consists of a plurality of capacitors and switches, wherein the capacitors from C1 to Cn are connected in parallel with the switches from K11 to K1(2n-1), and connected in series with the switches from K21 to K2(n-1); an input switch K1 and an output switch K2 are respectively connected in series with the capacitor parallel circuit and the capacitor series circuit; when the input switch K1 and the serially connected switches from K21 to K2(n-1) are turned on, the transformer is charged; when the output switch K2 and the shunt-wound switches from K11 to K1(2n-1) are turned on, the transformer is discharged; and the switches are repeatedly switched on/off to convert high-voltage electricity into low-voltage electricity. The capacitor transformer has the advantages of safety, reliability, less electromagnetic loss, simplicity and convenience in operation, low manufacturing cost, and the like.
