Title: Innovations of Harry J Bittner
Introduction
Harry J Bittner is a notable inventor based in Santa Clara, CA (US). He holds a total of 7 patents that showcase his contributions to the field of electrical engineering. His work primarily focuses on voltage regulation and semiconductor technology.
Latest Patents
One of his latest patents is a voltage regulator that operates in either PWM or PFM mode. This innovative switching voltage regulator achieves high efficiency by automatically switching between pulse frequency modulation (PFM) mode and pulse-width modulation (PWM) mode. The regulator monitors the output voltage and current, operating in PFM mode at small output currents and in PWM mode at moderate to large output currents. In PFM mode, it maintains a constant output voltage by forcing the switching device to skip cycles when the output voltage exceeds its nominal value. Conversely, in PWM mode, a PWM signal with a variable duty cycle controls the switching device, ensuring a constant output voltage through feedback circuitry that adjusts the duty cycle according to fluctuations in the output voltage.
Another significant patent is for a field effect transistor with a switchable body to source connection. This invention prevents forward biasing the diodes within an N-channel transistor by switchably connecting the body and source of the N-channel transistor via a high-voltage FET. The gates of both transistors are connected, allowing them to operate simultaneously. When activated, the high-voltage transistor shorts the body and source of the N-channel transistor. When deactivated, a third transistor couples the body to a reference potential, enabling multiple devices to connect to the same output terminal and form a voltage multiplexer.
