Title:
DC-DC CONVERTER
Document Type and Number:
Japanese Patent JP2019057991
Kind Code:
A
Abstract:
To reduce the loss of a DC-DC converter.SOLUTION: In a DC-DC converter 10, a plurality of series circuits comprising a series circuit of a lower FET 31 and an upper FET 32 and a series circuit of a lower FET 33 and an upper FET 34 are connected in parallel between high-potential output wiring 14 and low-potential output wiring 16. Diodes 42, 44 are connected in parallel to the upper FETs 32, 34, respectively. A main reactor 22 is connected to high-potential input wiring 12, a first sub reactor 24 is connected between the main reactor and the first lower FET 31, and a second sub reactor 26 is connected between the main reactor and the second lower FET 33. A gate control unit 54 has control means that does not turn on the upper FETs 32, 34 in a zero cross mode that has a period in which current flowing through the main reactor is zero.SELECTED DRAWING: Figure 1
