generator using instantaneous power control
... The appIication of load at the stator terminal causes the capacitor voltage to decrease as shown in the Fig. 3(a) due to insufficient active power produced by the IG to meet the active power demand by the load. Hence, the deficient active power required by the load is provided by the inverter. The c ...

... A bipolar junction transistor, BJT, is a single piece of silicon with two back-to-back P-N junctions. However, it cannot be made with two independent back-to-back diodes and is not symmetric. BJTs can be made either as PNP or as NPN. They have three regions and three terminals, emitter, base, and co ...

Current source
A current source is an electronic circuit that delivers or absorbs an electric current which is independent of the voltage across it.A current source is the dual of a voltage source. The term constant-current 'sink' is sometimes used for sources fed from a negative voltage supply. Figure 1 shows the schematic symbol for an ideal current source, driving a resistor load. There are two types - an independent current source (or sink) delivers a constant current. A dependent current source delivers a current which is proportional to some other voltage or current in the circuit.
