Abstract

A charge voltage calibration system comprises a power supply, a light string, a driver, and a calibration circuit. The driver comprises a capacitor, a switch, and a sense resistor. The switch, sense resistor, and light string are coupled in series to form a discharge path coupled in parallel with the capacitor. The calibration circuit comprises a controller, a DAC, a comparator, a memory device. The controller is configured to control the DAC to provide a reference voltage to the comparator, cause the power converter to supply a first charge voltage to the driver, cause the switch to transition from an off state to an on state to discharge stored energy in the capacitor through the discharge path, and store a value of the first charge voltage in the memory device in response to detection of voltage generated across the sense resistor being greater than or equal to the reference voltage.
