Basic LM317 current source I wondered if the subcircuit consisting of the LM317 and resistors Rs and Rc could form the basis for such a circuit if it were driven from a suitable control current. In ...

2. A better approach is to use a FET as a constant-current source. The IXTP3N50D2 Dmode FET from IXYS Corp. powers a 5-W white VLED such as the LZI-00NW05 from LEDengin (190 lumens at 1 A); the ...

In this circuit, a PNP transistor sources current. The base voltage is about 0.7 V less than the emitter voltage. So with 10.3 V on the base, the emitter has about 11 V and R1 sees about 1 V ...

Figure 2 shows another (easier) way to make Iout programmable. The circuit enables control of ampere-scale Iout with only milliamps of Ic control current. Figure 2 A modification that makes the ...

Edward Norton of Bell Labs developed his current source theorem back in 1926 as a way to realize an alternative kind of circuit analysis. A current source supplies a fixed current with high ...

Technical Terms Current Source Inverter: A device that converts a DC current from a constant current source into an AC output, commonly used in high-power applications.

Additionally, innovative concepts such as the three-phase boost-stage coupled current source inverter have simplified multilevel modulation schemes and reduced switch stress, which is critical in ...
