Latest Patents
One of his latest inventions is the Sea Water Battery Power Converter. This invention converts the voltage output of a DC source to a higher voltage. A germanium transistor start-up circuit receives a DC supply voltage input and includes an astable multivibrator that produces a square wave voltage output. This output is transformed to a substantially DC steady-state voltage output by a transformer and a capacitor. The elevated voltage is provided to an oscillator circuit, which generates two square wave outputs. Each output is connected to an array of inverters operably coupled to an array of field effect transistors. The transistors are linked to a power transformer, and the square wave outputs of the power transformer are full wave rectified to provide a DC output with a higher voltage than the system input voltage. Additionally, the power transformer provides another full wave rectified voltage that disables the start-up circuit to eliminate parasitic energy losses due to its continued oscillation.
Another significant invention by John L Henry is the Vector Summation Power Amplifier. This device sums a time sequence of square waves to produce minimum distortion in power voltage sinusoids. The phase difference of two identical sinusoids is varied to control the resultant summed amplitude. Amplitude modulation of the summed sinusoid is achieved by varying the phase relationship between the two identical sinusoids. Furthermore, frequency and phase modulation is accomplished through digital control of the individual square waves.
