Latest Patents

One of Jason's latest patents is titled "Input AC line control for AC-DC converters." This invention involves an AC-DC converter that includes a main switch controlled according to the input AC line voltage. The main switch can be activated when the input AC line voltage is within a specific regulation band, while it is prevented from being switched when outside this band. Notably, the regulation band can be dynamically adjusted based on load conditions. The AC-DC converter can function as a buck, boost, or buck-boost converter.

Another significant patent is "Optimization of PWM DC operating point of voltage regulators with wide operating range." This invention configures a pulse width modulation (PWM) DC operating point of a voltage regulator to be relatively independent of both input and output voltages. The drive transistor of the regulator is periodically switched ON to couple the input voltage to an output capacitor, generating the desired output voltage. A ramp signal is created by dividing a signal from the input voltage with another from the output voltage, which is then used to charge a capacitor. This ramp signal is compared to an error voltage indicative of the output voltage level to determine when to switch OFF the drive transistor.
