Abstract

The invention discloses a charger calibration device and a charger calibration method. The charger calibration device comprises a control module and a processing module. The control module controls a charger needed to be calibrated to carry out a first stage charging and a second stage charging to an electrical device. The processing module carries out a adjustment process according to the second stage charging time, so that high level quasi-periodicity of a pulse width modulating signal in a charging circuit of the charger need to be calibrated is adjusted. A preset high level quasi-periodicity is added or subtracted a preset adjustment range by the adjustment process, so that an updated high level quasi-periodicity is generated, then the preset adjustment range is reduced by half to generate an updated adjustment range, a calibration loop is repeated to preset times, and a calibration procedure is terminated.

Description

Technical field [0001] The present invention relates to a charger correction device, in particular to a lower cost and more efficient full-digit flash charger correction device and a correction method thereof. Background technique [0002] In digital cameras and digital cameras, the flash module is an indispensable component. In order to trigger the inert gas in the flash tube to shoot the flash, the flash circuit needs a charging capacitor to store energy. The charging voltage of this capacitor may be as high as 300 volts or more. Therefore, in order to be able to increase the capacitor voltage to a high voltage above 300 volts, a charging circuit is required in the flash lamp circuit to convert the energy of the battery into the capacitor. [0003] In the camera production process, in order to make all the produced cameras meet a specific technical specification, an upper limit is set for the flash charging time, so that each camera can have a similar charging time under the sam...
