Title:
VOLTAGE CONVERTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/199900
Kind Code:
A1
Abstract:
Provided is a voltage converting device capable of detecting an abnormality whereby a duty provided to a voltage converting portion does not converge to a normal range.
A voltage converting device (1) includes: an output voltage detecting portion which detects a value representing an output voltage of a voltage converting portion (6); a setting portion for setting a duty of a PWM signal which is provided to the voltage converting portion (6) in such a way that the output voltage value of the voltage converting portion (6) approaches a target voltage value; and a drive portion (4) which outputs to the voltage converting portion (6) the PWM signal of which the duty has been set by the setting portion. The voltage converting device (1) additionally includes an abnormality detecting portion for detecting an abnormality whereby, when the voltage converting portion (6) has reached a certain stable condition, the duty set by the setting portion does not converge to a certain regular range.
