Abstract:
1. A high voltage high current regulator circuit for being interposed between first and second terminals that are connected to an external circuit, comprising: a) a bidirectional current-regulating circuit connected between the first and second terminals for receiving and regulating current between the first and second terminals; the current-regulating circuit comprising at least one main-current carrying cold-cathode field emission electron tube that conducts current between the first and second terminals; the at least one main-current carrying cold-cathode field emission electron tube having first and second control grids for controlling current conduction between the first and second terminals when the voltage on the first and second terminals is positive and negative, respectively; and b) first and second grid-control cold-cathode field emission electron tubes respectively providing control signals for said first and second control grids.
