Title:
スイッチング電源
Document Type and Number:
Japanese Patent JP5664180
Kind Code:
B2
Abstract:
A switching power source according to one embodiment includes a first transistor and a second transistor. The first transistor is connected to a positive electrode of a DC voltage source. The second transistor is connected between the first transistor and a negative electrode of the DC voltage source. The first transistor and the second transistor are alternately placed in conducting state. A gate signal is applied to a gate terminal of the first transistor with reference to a voltage of a terminal of the first transistor that is connected to the positive electrode. A gate signal is applied to a gate terminal of the second transistor with reference to a voltage of a terminal of the second transistor that is connected to the negative electrode. The first transistor and the second transistor are configured with wide bandgap semiconductors of mutually different materials, respectively.
