Abstract: An off-board battery charger for a vehicle may include a high-voltage connector having first, second and power supply connector ports. The first connector port connects to a vehicle controller via a first cable. The second connector port connects to a vehicle battery via a second cable. And, the power supply connector port is electrically connected with the second port and receives power via a power supply cable from a separate and external power supply.

Abstract: An adjustable output level transmitter includes a direct current energy source, an L-C tank circuit and a switching means for sequentially coupling the capacitors of the tank circuit to the direct current energy source and ground. The output signal frequency is equal to the resonant frequency of the L-C tank circuit and the output signal level is a function of which capacitors of the L-C tank circuit are sequentially coupled to the energy source. The circuit functions in a Class D mode with the inherent advantages of minimal power loss and very high efficiency. Due to the manner of switching utilized, the output signal frequency is very stable and unaffected by the mode of capacitor switching.
Abstract: A compact lightweight high power RF generator for use in military systems combines the principles of vector inversion transform systems with a RF tank circuit. The capacitively stored energy in the lines is discharged by means of high speed switching techniques with the energy store being a part of the tuned circuit.
