Title:
SWITCHING POWER SOURCE DEVICE AND ERROR CORRECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2017/094402
Kind Code:
A1
Abstract:
The output current size of a converter (11A), said output current size being detected while a converter (11B) is stopped, is transmitted to a measurement jig, and the output current size of the converter (11B), said output current size being detected while the converter (11A) is stopped, is transmitted to the measurement jig. A correction value that is determined with the measurement jig on the basis of the content of the transmissions is received and stored in memory (175). The output current size (detected current value I1) of the converter (11A), said output current size being used during PWM control, and the output current size (detected current value I2) of the converter (11B), said output current size being used during PWM control, are each corrected using the correction value. As a result, provided are a switching power source device and an error correction method that can correct variation in output current for each converter.
