Title:
SWITCHING ELEMENT DRIVING DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/203691
Kind Code:
A1
Abstract:
This switching element driving device includes: a driving circuit (2) that is connected between an element driving power source and a circuit ground and outputs a driving signal to a switching element (5) to be driven; a capacitor (6) that is connected between the circuit ground and a reference ground to which a reference potential side conduction terminal of the switching element to be driven is connected; and a regulator (3) that performs a charging/discharging operation so that the capacitor has a predetermined terminal voltage. The regulator performs the discharging operation when the terminal voltage exceeds an upper limit and performs the charging operation when the terminal voltage falls below a lower limit.
