Title:
IN-VEHICLE DC-DC CONVERTER
Document Type and Number:
WIPO Patent Application WO/2019/150900
Kind Code:
A1
Abstract:
The present invention provides a configuration capable of suppressing a peak value of a current flowing through an inductor when an output current is increased, while preventing an increase in the size of the inductor. An in-vehicle DC-DC converter (1) includes a calculation unit (32A) and a frequency setting unit (32B). The frequency setting unit (32B) sets a frequency of a PWM signal at a first frequency when an output side conductive passage is in a predetermined normal current state on the basis of a value of a current detected by a current detecting unit (44), and sets the frequency of the PWM signal at a second frequency higher than the first frequency when the output side conductive passage is in a predetermined high current state.
