GROUND REFERENCE GENERATOR FOR POWER CONVERTER
This abstract first appeared for US patent application 20240429819 titled 'GROUND REFERENCE GENERATOR FOR POWER CONVERTER
Original Abstract Submitted
a ground reference circuit to generate a ground reference for a voltage reference circuit includes a resistor coupled in series with a transistor via a current mirror. the resistor is coupled between a ground reference terminal of the voltage reference circuit and a ground terminal of a power converter. the transistor control terminal is configured to receive a pulse width modulation (pwm) control signal having a duty cycle similar to a switching element duty cycle of the power converter. the current mirror circuit is coupled between a current terminal of the transistor and the ground reference terminal. a controller configured to control the switching element duty cycle may include the ground reference circuit, along with the voltage reference circuit, and a pwm circuit configured to determine the switching element duty cycle based on a comparison between a reference voltage provided by the voltage reference circuit and the converter output voltage.
