A Series-Tuned Inductive-Power-Transfer Pickup With a Controllable AC-Voltage Output

AC Processing Controllers for IPT Systems

“…The inductor current and capacitor voltage are both sinusoidal having low distortion at 100% power. The small voltage overshoots across the switch result from snubber oscillations as discussed in (Wu et al, 2011c). The measurements as shown have excellent correlation with analytically calculated waveforms in (Wu et al, 2011c) with amplitudes that are within 10% of the calculated values.…”

Since the series AC processing pickup has an AC voltage source property, it can be used to drive incandescent lights.…”

“…A series AC processing pickup as described above was constructed with parameters in (Wu et al, 2011c). Fig.…”

“…This modified topology eliminates the need for an extra buck converter stage, improves efficiency and reduces cost. In addition, the circuit has the ability to control and eliminate the transient inrush current during start up (Wu et al, 2011c). Preliminary experimental results show that the pickup regulator operates with high efficiency.…”

“…The analysis of the series AC processing pickup is very similar to the parallel and can be found in (Wu et al, 2011c). In this section, the operating characteristics of the series AC processing pickup are presented in comparison to the parallel AC processing pickup.…”
