POWER HARVESTING CIRCUIT

Номер: US20190011940A1
Автор: BEZOS Angel P., FERNANDEZ Emilio A.
Принадлежит:

A power harvesting system employs a saturable core transformer having two primary windings and at least one secondary winding. One of the primary windings is a high impedance winding, and the other primary winding is a low impedance winding. The two primary windings are connected with the load (motor). The secondary winding provides power to the circuit components of a replacement electronic thermostat. Relay contacts connects A/C power to either the high impedance primary winding or to the low impedance primary winding. When the relay is de-energized, A/C power is applied to the high impedance winding so that a relatively small amount of current flows through both the high impedance winding and the load. This current is low enough that it does not energize the load but is sufficient to generate the required voltage to transfer power to the secondary winding. This power can be used to power an electronic thermostat. When the relay is energized, A/C power is applied directly to the low impedance primary winding, energizing the load. At the beginning of each A/C cycle, the current through the low impedance winding builds up rapidly until the core saturates. The result is that a short pulse is generated in the secondary on both the positive and negative A/C cycle. This pulse has an amplitude determined by the turns ratio of the low impedance winding to the secondary winding and is used to power the electronic thermostat. After the core saturates, the impedance of the low impedance winding is only the resistance of the wire of the winding which is relatively small and results in negligible impact on the load. 1. A power harvesting system comprising:a transformer having first and second primary windings and a secondary winding, the first primary winding being a high impedance winding with a large number of turns and the second primary winding being a low impedance winding with a small number of turns, the first and second primary windings connected with a load, the ...
