Title:
DC-DC CONVERTER
Document Type and Number:
WIPO Patent Application WO/2017/038294
Kind Code:
A1
Abstract:
A full bridge circuit (10) is connected to a primary winding wire (n1) of a transformer (T1), and a full bridge circuit (20) is connected to a secondary winding wire (n2) of the transformer. The full bridge circuit (10) has: a first series circuit of switching elements (Q1-Q4); a second series circuit of switching elements (Q5-Q8); a first charge/discharge capacitor (Cf1) connected to a connection point between the switching elements (Q1, Q2) and a connection point between the switching elements (Q3, Q4); and a second charge/discharge capacitor (Cf2) connected to a connection point between the switching elements (Q5, 6), and a connection point between the switching elements (Q7, Q8). The full bridge circuit (10) operates in full bridge operation mode and/or half bridge operation mode. Consequently, a DC-DC converter, which is capable of constantly performing highly efficient operations even if a load fluctuation range is broad, is provided.
