PCT No. PCT/EP94/02375 Sec. 371 Date Apr. 8, 1996 Sec. 102(e) Date Apr. 8, 1996 PCT Filed Jul. 19, 1994 PCT Pub. No. WO95/03681 PCT Pub. Date Feb. 2, 1995An apparatus supplies an ohmic, inductive or capacitive load with needle pulse trains in which each individual pulse has a duration of less than 1 millisecond. Due to pulse amplitudes which are by far higher in relation to the nominal voltage of the load, considerable increases in efficiency can be achieved, however, without damaging the load or impairing its useful life. The needle pulses are of constant amplitude and the same polarity. The ratio between pulse voltage and nominal voltage is always higher than 1.7. |
