Title: John E White: Innovator in Power Amplification and Current Limiting Technologies
Introduction
John E White is a notable inventor based in Port Moody, Canada. He has made significant contributions to the field of power amplification and current limiting technologies. With a total of 2 patents to his name, his work reflects a deep understanding of electrical engineering principles.
Latest Patents
One of John E White's latest patents is a "Switch mode - class B power amplifier." This invention involves applying an input signal to the inverting input of a class B amplifier and to a limiter circuit. The square wave signal from the limiter is then applied to a switching amplifier, which drives the amplifier between V and ground at a rate established by the input signal. This process results in a power control signal that is applied to a load and the non-inverting input of the class B amplifier. The output of the amplifier switches between V and ground, producing an output signal that mirrors the input signal with a peak-to-peak amplitude of 2V.
Another significant patent is the "Transformerless fast current limiter with symmetry correction for a switched mode power supply." This invention utilizes a pulse width modulation controlled DC-to-DC converter to regulate power from a source of DC voltage. A transformerless current-sensing device is integrated into the path between the source and the converter, providing a control signal representative of the current flow. A current-limiter control circuit responds to this signal, enabling an output state when the sensed current exceeds a predetermined value, thus terminating the output pulse.
