Filed: 1971-12-23
Abstract: 1335777 Waveform generator TEXACO DEVELOPMENT CORP 23 Dec 1971 [30 Dec 1970] 60198/71 Heading G4H [Also in Division G1] A control circuit, for providing repeated energization of an ion accelerator neutron source and gating of a detector in a borehole logging sonde, produces 985 pulses at a frequency of 1000 pulses/sec., in the first 985 msecs. of each one second cycle, the first 984 being negative and the final one being positive. Clock pulses from 80 feed a ten flip-flop counter 100 and an AND gate 93 via delay 82 which prevents racing. Negative pulses are thus generated by 83, until at the 984th, gate 92 is opened to cause flip-flop 111 to close gate 93 and ensure that the 985th pulse is positive instead of negative. Gate 93 remains closed for the next 15 msecs. until at 999 all flip-flops 101-110 and 111 are reset due to actuation of monostable 81 in readiness for the next 1 sec. cycle.

Patent GB-2048588-A (GB)
Title: Direct A.C. to A.C. converter
IPC: H02M1/084
Filed: 1980-02-27
Abstract: The converter converts a polyphase a.c. input supply (117-119) into a single or polyphase a.c. supply (120-122) of amplitude, phase, frequency or power factor which is different from the input supply using a matrix of bi-directional switches (SM1-SM9) having contiguous width modulated conduction periods in cycles which synthesise the output supply voltage or voltages from samples of the input supply voltages taken cyclically at a much higher frequency that the supply frequency or frequencies. The switches are operated so that the or each output supply conductor is always connected to only one of the input supply conductors at a time. The width modulation may be effected in response to phases of a sinusoidal oscillation (100) to produce a frequency change. The output may have a "negative" frequency so that a phase displacement between current and voltage due to a reactive load appears in the opposite sense in the input supply. Width modulation may alternatively be effected by a combination of two sinusoidal oscillations so that the output frequency has equal positive and negative values to eliminate phase displacements in the input supply due to a reactive load. Motor speed control and generator output frequency control applications are described. <IMAGE>
