Goffeau, J R

An improved up-and-down chopper circuit is described which is useful for voltage regulation in a bi-directional dc power system. In the down mode, power is switched from a dc power source to a lower voltage energy storing load while in the up mode stored energy in the load is transferred to the higher voltage source. The system uses Darlington transistor switches in a conventional connection. The improvement relates to circuit additions to eliminate the effects of inter-electrode capacitance inherent with this Darlington transistor switching arrangement.
