Title: A modulator for a switching power supply with a rapidly varying output
Inventor: WILSON MARTIN
IPC: H02M3/155
Filed: 2008-04-18
Abstract: In a pulse width modulator controlling a buck switching power supply for mobile radio transmission apparatus, comparators 4008,4010 compare the modulating signal 4002 with respective falling and rising ramps to respectively set and reset the output flip-flop 4028 through edge-triggered pulse generators 4014,4012. There may be more than one output transition per cycle (cycle 2 in figure 2) and the output state is not reset between cycles. Rapid tracking of the input is achieved without unnecessary switching. Two or more sets of complementary ramps (figure 4) may be used, and there may be three or more output voltage levels (figure 9). Matching of the ramps to the voltage levels in a multi-level modulator may be achieved by use of a current-mode circuit (figure 10).

Filed: 1920-04-13
Abstract: 141,718. Fort-ified Manufacturing Co., (Assignees of Fort, G. L.). Oct. 4, 1916, [Convention date]. Metal pots.-Metal is supplied to the metal-pots of type-bar-making machines from an auxiliary melting-device which is electrically heated and is controlled by a float so as to maintain a constant level in the metal-pot. The auxiliary metalpot 14 is pivotally mounted on the machine frame 1 by means of a clamp 12 and a standard 13, and comprises a cylindrical container 18 to receive the ends of metal pigs 19. The container is surrounded by heating-coils 23 enclosed in a non- conducting casing 28, and is surmounted by a casing 34, having a hinged section, by which the pigs are supported. The container has a sloping base 20 and a spout 22 delivering to the main metal-pot 2. Current is supplied to the heating- coils 23 from circuit wires 45, 46 through wires 43, 44, the wire 44 being connected to a solenoid 61 the core of which is carried by a pivoted contact-lever 70. The current is automatically controlled by a float 47 carried by a rod 48 having adjustable collars 50, 50<1> which are adapted to rock a pivoted contact-lever 54 moving between contacts 58, 59. As the level in the pot 2 falls, the lever 54 engages the contact 58 and a current passes through the heating-coils. The solenoid 61 then attracts its core so as to rock the contactlever 70, whereby the current is shunted past the lever 54 and caused to pass through the lever 70. As fresh metal is supplied, the float rises until the lever 54 meets the contact 59. The solenoid 61 is thereby short-circuited and the lever 70 is raised by a spring and the circuit broken. An additional heating-coil may be located below the container 18, or the container may be of tapered form.
