Claim Text:
1. A benistor controllable electron valve system for controlling simultaneously the voltage and current amount of nonlinear loads such as LEDs in a linear and self-switching mode of operations, the system comprising: at least one of a power controller (PC) and a buffer (BUF) sub-circuit comprising: a current separator (CS) or mixed signal processor (uC) sub-circuit operatively connected to the PC gate control terminal including at least one of a plurality of diodes and a plurality of open collector buffer transistors to allow interconnections between outputs of two or more combinations of analog operational amplifiers and analog to digital converters to allow mixed signal control of the PC sub-circuit output parameters in feedback with a plurality of signals received via its input terminals, processed versus internal reference voltages and/or data; a temperature sensor (Ts) sub-circuit operatively coupled to the uC sub-circuit to secure the PC sub-circuit's operations consistency despite large variations of the driver system internal and/or environmental temperature; a voltage reference sub-circuit operatively coupled to the uC sub-circuit and to a zero voltage reference terminal (ZVR) to secure reliable internal voltage references despite large variations of the operation temperature; a two input, one output terminal ON voltage threshold control sub-circuit (VTCon) comprising: a voltage on (Von) input terminal coupled to a reference voltage; a sensing voltage input terminal (Vs) coupled to a variable voltage source and the output terminal operatively coupled to the uC sub-circuit to switch ON the PC sub-circuit anode-cathode terminals (A-K) junction when the Vs terminal's voltage amount is lower than the Von terminal's voltage amount and to switch off the PC sub-circuit's A-K junction when the Vs terminal's voltage amount is higher than the Von terminal's voltage amount; a two input, one output terminal OFF voltage threshold control sub-circuit (VTCoff) including a voltage off (Voff) input terminal coupled to a reference voltage, a sensing voltage input terminal coupled together with the Vs terminal of the VTCon sub-circuit and the output terminal operatively coupled to the uC sub-circuit for switching off the PC sub-circuit anode-cathode terminals (A-K) junction when the Vs terminal's voltage amount is lower than the Voff terminal's voltage amount and to switch on the PC sub-circuit's A-K junction when the Vs terminal's voltage amount is higher than the Voff terminal's voltage amount; a two input, one output terminal current control (CC) sub-circuit comprising a negative feedback control (Cc) input terminal coupled to a variable voltage source, a reference voltage input terminal coupled to a voltage reference source and the output terminal operatively coupled to the uC sub-circuit to increase the dynamical resistance of PC sub-circuit anode-cathode terminals (A-K) junction and implicitly decrease the A-K circuit's passing current when the Cc terminal's voltage amount is higher than the reference voltage terminal's voltage amount and to decrease the dynamical resistance of PC sub-circuit anode-cathode terminals (A-K) junction and implicitly increase the A-K circuit's passing current when the Cc terminal's voltage amount is lower than the reference voltage terminal's voltage amount; and a feedback (FB) terminal to allow operative access to the PC sub-circuit, via the uC sub-circuit for feedback, synchronization and shutting down operations, wherein said FB terminal's function could be overtaken by said Cc terminal and/or by said VTCOff terminal and/or by said VTCon terminal.
