Title:
SWITCHING CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/173381
Kind Code:
A1
Abstract:
A drive circuit (21A) is connected to a gate terminal (g1) of an FET (Q1) and turns on the FET (Q1) by applying a voltage to the gate terminal (g1), wherein the FET (Q1) is connected to a DC power supply (VPP) to be transformed, is controlled to be on or off, and has a drain terminal (d1) to which current is input, a source terminal (s1) for outputting the current input from the drain terminal (d1), and the gate terminal (g1) for controlling the current flowing from the drain terminal (d1) to the source terminal (s1). A reverse bias circuit (22A) has a capacitor (C4) connected to the source terminal (s1) of the FET (Q1) and a coil (L1), one end of which is connected between the drive circuit (21A) and the gate terminal (g1) and the other end of which is connected between the capacitor (C4) and the source terminal (s1), so that an effect can be attained that the number of components constituting the reverse bias circuit (22A) is prevented from increasing.
