Title: Throughflow converter - has transformer with prim. winding via which first controlled switch is at input DC voltage and two sec. windings with common base
Inventor: LIEGL GUENTHER DIPL ING
IPC: H02M3/335
Filed: 1992-07-10
Abstract: The power supply uses a transformer (TR) with one primary coil (LP) supplied with DC via a switch (S1) and two secondary windings (L1, L2). One terminal of each secondary winding is connected to a common (negative) point, the other ends of the windings being connected to respective rectifier diodes (D1, D2) and reservoir capacitors (C1, C2) to produce first and second output DC voltages (U1, U2). The first secondary winding circuit also includes a freewheeling diode (D3) connected between the rectifier diode cathode and the negative line and an energy storage coil (SDR) in series with the rectified output. Control circuits (RS1, RS2) vary, as a function of the two output voltages, the respective duty cycles of the primary winding switch and a second switch (S2) which connects together the cathodes of the rectifier diodes. The duty cycle of the second control circuit is set so that the second switch is synchronized with the first switch and switches on only after the first switch is turned off. 
-USE/ADVANTAGE :  
As a switching type DC-DC converter, such as a SMPS using a flyback DC-DC converter. The circuit configuration provides a compact and inexpensive switching power supply with two separate regulated output voltages having a high degree of independence. Since the switching frequency remains constant, components such as the transformer can be dimensioned accordingly.

Title: Method and device for attacking (engaging) target objects by submunitions
Inventor: TROSKY BERNHARD
IPC: F42B12/58
Filed: 1993-02-11
Abstract: A method and a device (18) are described for attacking target objects (10) with submunitions (24) which are provided in a warhead (22) which is put into a ballistic flight path (trajectory) (28) by means of a motor (20). When on the flight path (28), the motor (20) is separated from the warhead (22), after which the submunitions (24) are released from the warhead (22) at a specific release altitude (height) (Hf). In order to achieve a reduction in the scatter area of the submunitions (24) in a target area (12), the release altitude (Hf) is fixed in a defined manner irrespective of the ballistic flight path (28) of the device (18). To this end, the current altitude-dependent air pressure is measured by means of a pressure sensor (40) before (in time) the separation of the warhead (22) from the motor (20), and is converted into the corresponding current altitude by means of a processor (38). The calculated altitude is compared with the preprogrammed release altitude (Hf), and the tumbling falling time of the warhead (22) is correspondingly adjusted. <IMAGE>
