Abstract

The patent refers to a sensor-multi-output circuit system and a method of operating a sensor-multi-output converter. This sensor-multi-output circuit system includes: a sensor; the output leads of the converter; switching output voltage switching circuits in response to the input voltage supplied to the sensor, according to segmented sensing cycles, in which each of these sensing cycles includes a charging phase in which the sensor receives input voltage and is electrically connected to a specific converter output line among the many converter output lines and a conducting phase in which the sensor is disconnected from input voltage and is electrically connected to a corresponding converter output line other than the specific converter output line among the many converter output lines;At least one ripple detector is electrically connected to the output line of the relevant converter among the converter output lines, to detect ripple of the switching output voltage at the relevant converter output line; a switching controller is configured to control the switches based on the ripple voltage corresponding to the ripple detected by at least one ripple detector, to control the switching output voltage; and at least one regulator is configured to dynamically set a predetermined target output voltage specific to the relevant regulator at the output line of the relevant converter among the converter output lines; and the switching output voltage is regulated within a predetermined range from the target output voltage by using current from another converter output line among the converter output lines.
