Abstract
1353794 Cardiac pacemakers WILSON GREATBATOH Ltd 29 April 1971 [29 April 1970] 12153/71 Heading A5R [Also in Division H2] A voltage multiplier (e.g. for supplying power to a cardiac pacemaker) comprises a plurality of capacitors 86, 89, 92 charged in parallel from a supply 83 and discharged in series via a load 99 under control of triggered switching devices such as transistors 100, 101, 102. The load 99 is connected in the charging path of one of the capacitors 92 so that the average load current over a complete cycle is zero. As described, the source 83 may be a 0.8V rechargeable cell or a nuclear battery delivering from 0.2-0.75V. The discharging transistors 100..102 may be triggered by a pulse generator 120 which may comprise a low power oscillator driven by a tunnel diode r.f. converter. The trigger pulses are coupled to the discharging transistors 100, 101, 102 via an emitter follower 124. Voltage regulation. During each cycle, whenever the voltage across load 99 (simulating the pacemaker) reaches a value determined by the setting of potentiometer 135, transistor 136 becomes conductive short-circuiting the pulses to emitter follower 125 and terminating the charge. The transistors 100, 101, 102 may be germanium, silicon or field-effect transistors.
