摘要： An inductive power transfer pickup circuit has a pickup coil (L2) and tuning capacitor (C2) connected in series to provide a series resonant circuit. A bi-directional switch (S1) is used to vary the phase angle between the open circuit pickup coil voltage (Voc) and the pickup coil inductor current (iL) to provide a controlled AC supply to an output of the pickup.
