ABSTRACT:
A regulator circuit for use with a connectorless power supply system in which power is inductively supplied to a plurality of remote loads. A sinusoidal current, at a frequency of 38 kHz, is provided by a power distribution system (10), and circulates through a supply loop (68), which is disposed under the floor of an aircraft cabin. Three parallel connected capacitors (78, 80, and 82) and a multi-turn coil (70) that is inductively coupled to the supply loop comprise a resonant tank circuit in which current circulates. The voltage developed across the tank circuit is half wave rectified, filtered, and supplied to a load connected circuit. An op-amp (134) compares the potential across the load to a regulated voltage. The output of the op-amp is used to control the period of time during which an N channel FET (96) shunts current to regulate the output voltage. Because the N channel FET is only permitted to shunt current to control the output voltage when the potential of the AC current flowing in the tank circuit passes through zero with a negative slope, the regulator circuit produces minimal EMI. The regulator circuit controls the output voltage with respect to variations in the inductive coupling between the supply loop and the pickup coil, and with respect to variations in the connected load.
