摘要： A transmission cable system that incorporates cooling channels that encircles electrical conductors with coolant. The transmission cable system also provides for breach or leak detection. More specifically, the transmission cable system maybe used with an inductive charging system that transfers electric power from a power source to batteries of an electric vehicle. The cable system includes a cooling system for storing, cooling, and pumping coolant, and a pressure sensitive switch for determining the pressure in the cooling system and for providing an output signal indicative of a drop in sensed pressure. A controller is coupled to the pressure sensitive switch that is responsive to the output signal from the switch for shutting down the inductive charging system in the event of a drop in sensed pressure. The transmission cable is electrically coupled between the power source and the electric vehicle for coupling electrical power to the batteries. The transmission cable is also coupled between the cooling system and the inductive charging system and includes a plurality of coolant channels that permit the flow of coolant between the cooling system and the inductive charging system that cools the transmission cable when transferring electrical power.

摘要： A circuit for converting on d.c. voltage to another d.c. voltage including a transformer having a center tap and first and second end leads. A d.c. source voltage is connected to the center tap of the transformer. The end leads are connected to ground through first and second MOSFETs and to the gate of the MOSFET through which the other end lead is connected to ground such that the circuit is nominally self-oscillating due to transformer saturation. Current spikes may be minimized with a control circuit, consisting of an oscillator, a flip-flop, and first and second transistors, connected to the gates of the first and second MOSFETs. The control circuit turns the MOSFETS off prior to their natural oscillation turn off caused by transformer saturation. The circuit is particularly suited to operation with a low voltage d.c. source and low voltage MOSFETS.

摘要： A current controlled voltage boost circuit for a high voltage converter. The voltage boost circuit includes a boost converter connected to receive an input voltage and a control signal, and output an increased output voltage to the high voltage converter as a function of a control signal. The circuit further includes a current sensing circuit providing an output voltage proportional to the sensed input current to the high voltage converter. The output voltage from the current sense circuit varies a reference voltage that is compared to the boost converter output voltage by an error amplifier. The error amplifier, in turn, outputs a control signal to the boost converter such that the control signal controls the boost converter output voltage as a function of the input current to the high voltage converter.

摘要： A high voltage cable system for use with a contactless battery charging system that charge propulsion batteries of an electric vehicle, and the like. The contactless battery charging system includes a primary power converter coupled to a power source and a secondary power converter located on the electric vehicle that is coupled propulsion batteries of the electric vehicle. The primary and secondary power converters are connected by way of a coaxial power cable. An isolation transformer is coupled between the output of the primary power converter and the coaxial power cable. This transformer allows one of the two outputs of the primary power converter to be connected to ground potential. The isolation transformer improves the safety and reduces electromagnetic interference (EMI) when coupling power to the secondary power converter. The isolation transformer 30 allows for the use of a stepped-up voltage level to be used in the primary power converter, which reduces the amount of current in the coaxial power cable required to deliver power to the secondary converter. This allows a much higher charge power to be delivered to the electric vehicle using a reasonably sized coaxial power cable.

摘要： An inductive charge port for an electric vehicle in which part of the inductive coupling transformer core is attached to the inside of an access door on the vehicle, and wherein only a primary coil assembly is inserted into the charging device when charging the vehicle. The charge port includes a primary coil assembly having a primary winding that is coupled by way of an electrical cable to a power source, and a secondary coil assembly disposed in the vehicle. A housing in the vehicle has the secondary coil assembly disposed therein. The secondary coil assembly includes a transformer core having a first portion disposed in the housing. A secondary winding is disposed in a cavity in the first portion of the transformer core which receives the primary winding therein. A hinged access door has a compressible, resilient member disposed on its inner wall and a second portion of the transformer core is secured to the compressible member. The second portion of the transformer core forms a lid or cap that mates with the first portion to form a complete transformer core. The mating first and second portions tightly secure the primary winding in the cavity when the door is closed. The secondary winding is coupled by way of an electrical cable to a charging circuit that is coupled to a battery of the vehicle. When the primary coil is inserted into the cavity and the external power source is energized, power flows from the power source through the inductive charge port to the battery. The present invention provides for an easy and safe inductive coupling that eliminates the possibility of shock hazard to a user when recharging the electric vehicle.
