| 摘要 |
The device has an electrical circuit with a double voltage source of two voltage sources (U1, U2) connected together by one of the poles of a load circuit by four separate branches. The supplemental switches (SW1, SW2) produce two slopes of increasing and decreasing currents by selective connection of the branches. The branches return the excess self-induction energy of the electrical circuit to the double source. - The load circuit comprises an electrode-tool (EO) and an electrode-workpiece (EP) constituting opposite poles. The transfer unit transfers the energy between the two voltage sources of the double source.
