A DC current sensor has a core having a magnetically permeable material. A permeability measurement winding is formed around at least a portion of the core. The core is placed within a magnetic field of a conductor such that measurement of a permeability of the core via the permeability measurement winding facilitates determination of current flow through the conductor.

An inductor comprising one or more windings disposed on opposed first and second surfaces of a flat-plate substrate. The windings are applied to the substrate by plating or photoresistive deposition techniques, with through-holes through the plate accommodating the windings from opposed surfaces. Windings of more than one layer are obtainable with insulation between adjacent layers. The resulting inductor is usable, for example, as a component of an EMI filter in a power converter circuit.

A DC-DC converter suitable for multiple converter circuit topologies is disclosed. The DC-DC converter utilizes magnetic feedback of the output load current to provide broad inductance control of a magnetic element, while inhibiting saturation of the switched winding or windings of the magnetic element.

A linear variable differential transformer (LVDT) system is disclosed. The system has an LVDT. A signal conditioner circuit is coupled to the LVDT. The signal conditioner circuit uses an inductance of the LVDT primary as a micro-power excitation carrier frequency to lower a drive power of the system. The signal conditioner circuit generates output currents that are summed and filtered to generate a position proportional voltage.

A switch comprising a plurality of transformers and a path comprising a number of wires. Each of the plurality of transformers comprises a core and a control winding. The path is configured to connect the plurality of transformers to each other. Non-direct current flows through the path. Direct current is sent into the control winding for each of a portion of the plurality of transformers to saturate the core for the each of the portion of the plurality of transformers such that a transfer of energy between the core for the each of the portion of the plurality of transformers and the path is substantially absent.

A device for augmenting the control of a forced air furnace includes a heat probe which is located in association with a furnace heat exchanger so as to sense the air temperature of air passing across the heat exchanger. The probe is connected via a buffer to an optical controlled switch. A latch is associated with both the probe and the switch such that in response to a high temperature turn off point the optical coupled switch shuts off the furnace solenoid associated with the furnace and maintains the solenoid in an off position until the probe senses a low temperature turn on point. Upon sensing the low temperature turn on point the solenoid is turned back on and is maintained in the on position by the latch until the high temperature point is again reached.
