Latest Patents

One of his latest patents is titled "Heat sink and circuit enclosure for high power electronic circuits." This invention describes a triangular heat sink and circuit enclosure designed for high power dissipation electronic circuits. The heat sink incorporates multiple cooling fins to effectively cool the circuitry and equipment contained within the enclosure, capable of handling power dissipation levels of up to 15 kilowatts. The circuit enclosure utilizes air moving devices and triangular heat sinks to facilitate both conduction cooling and heat transfer to a stream of air. Notably, the cooling fins are sealed away from the electronic components when the circuit enclosure is assembled.

Another significant patent by North is "Feedback control of an inverter output bridge and motor system." This invention provides a method to maintain the rotational speed and the relationship of the electromagnetic fields of a three-phase induction motor. It determines the minimum voltage required to excite the motor without stalling. The three-phase induction motor is driven by an inverter bridge circuit that converts DC input power into three-phase AC output power. Feedback of the current supplied to the inverter bridge circuit is divided into positive and negative current flow periods, which are utilized to adjust the three-phase AC power magnitudes and phase angles. The inverter bridge circuit employs six insulated gate bipolar transistors to control these parameters.
