PCT No. PCT/SE85/00461 Sec. 371 Date Jun. 30, 1986 Sec. 102(e) Date Jun. 30, 1986 PCT Filed Nov. 18, 1985 PCT Pub. No. WO86/03349 PCT Pub. Date Jun. 5, 1986.A hacker type D.C. converter circuit having protective circuit features. The converter circuit includes a supply voltage source, and a series circuit including a first coil, a first diode and a first capacitor. The series circuit is connected to the supply voltage source. In addition, there is included a controllable switching arrangement, a connection junction between the first coil and first diode, and a further diode coupling across the switching arrangement. The first capacitor includes a first terminal remote from said further diode and a second terminal proximate the further diode. The connection junction is connected to the first terminal of the first capacitor remote from the further diode across the controllable switching arrangement which periodically alternates between open and closed states. The series between the connection junction and the first diode further includes an inductor and a second coil which is inductively connected to the first coil. A second diode is connected in a parallel circuit from the connection junction mentioned above and across the first diode of the first capacitor. |
