A voltage source Class-D inverter was exploited for the first time in a test rig for IPT rectifier characterisation independent of the magnetic link. The developed test rig makes the measurement of ac power feasible with commercially available passive voltage and current probes. while providing IPT conditions for the circuits …

Fig. 4 shows the die photo of a 5-6 GHz low-noise lowpower I Q DRC in 0.18μm CMOS technology. and the die-size is 1.5 x 1 mm2 including the DC RF pads. By on-wafer measurement. the total current consumption is 4.75mA at the supply voltage of 1.8 V. Fig. 5 …

Generation maintenance scheduling (GMS) plays an important role in power system operations. The restructuring of the power industry has forced changes to the traditional maintenance mechanism. On one hand. the generation companies seek to maximize their profit. On the other hand. the independent system operator (ISO) strives to maintain the …
