Title:
ISOLATED DC-DC CONVERTER
Document Type and Number:
WIPO Patent Application WO/2020/255720
Kind Code:
A1
Abstract:
An isolated DC-DC converter (100) is provided with a transformer (10), a full bridge switching circuit (20), a protection circuit (21), a control unit (40), an inductor (13), and an output circuit (30). The isolated DC-DC converter (100) is provided with a first voltage detection unit (40A) for detecting a voltage value between a first conductive path (1) and a second conductive path (2), and a first current detection unit (40C) for detecting a current value of the inductor (13). The control unit (40) determines at least one of a first dead time and a second dead time according to a system whereby, on the basis of the voltage value detected by the first voltage detection unit (40A) and the current value detected by the first current detection unit (40C), the dead time is increased as the voltage value increases and the dead time is decreased as the current value increases.
