A relay is operable in a first state to connect A/C power to the first primary winding and in a second state to connect A/C power to the second primary winding. When A/C power is connected to the first primary winding, a small current flows in the first primary winding which is insufficient to activate the load but sufficient to transfer power to the secondary winding. When A/C power is connected to the second primary winding, a larger current flows in the second primary winding sufficient to activate the load and to transfer power to the secondary winding.

  • Patent number: 9438033
    Abstract: Electrostatic discharge (ESD) protection devices can protect electronic circuits. In the context of radio frequency (RF) circuits and the like, the insertion loss of conventional ESD protection devices can be undesirable. The amounts of parasitic capacitances at nodes of devices of an ESD protection device are not necessarily symmetrical, with respect to the substrate. Disclosed are techniques which decrease the parasitic capacitances at signal nodes, which improve the insertion loss characteristics of ESD protection devices.

  • Patent number: 9369058
    Abstract: An inductive power transfer (IPT) control method is disclosed for controlling the output of an IPT pick-up. The invention involves selectively shunting first and second diodes of a diode bridge to selectively rectify an AC current input for supply to a load, or recirculate the AC current to a resonant circuit coupled to the input of the controller. By controlling the proportion of each positive-negative cycle of the AC input which is rectified/recirculated, the output is regulated. Also disclosed is an IPT controller adapted to perform the method, an IPT pick-up incorporating the IPT controller, and an IPT system incorporating at least one such IPT pick-up.
