Abstract
A high-voltage power supply circuit consisting of an amplifier, a sine wave generating circuit, an AC/DC converter, a microcontroller, a transformer, a rectifier diode, a filter capacitor, a first switch, and a second switch, in which the execution of the control program of the microcontroller controls the setting of the frequency of the sine wave signal, the start of the sine wave signal, the end of the sine wave signal, and the opening or closing of the relay switches; in which the sine wave signal from the sine wave generating circuit is amplified by an amplifier, boosted by a transformer, then rectified by a rectifier diode, and then filtered by a filter capacitor for output, or for feeding back to a negative terminal of the amplifier for comparison with the voltage at its positive terminal so as to stabilize the output voltage; and in which the execution of the control program of the microcontroller can also control the filter capacitor to discharge the voltage and the transformer to prevent damage to the switches.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
