摘要
The upper arm drive circuit for controlling drive of the upper arm switching element of the power conversion device includes: a capacitor disposed between a gate of the upper switching element and the output terminal of the power conversion device; a reverse current prevention circuit that is disposed between a power supply of the power conversion device and the capacitor, and that makes a current flow from a first terminal side of the reverse current prevention circuit connected to the power supply side to a second terminal side of the reverse current prevention circuit connected to the capacitor side and prevents a reverse current from flowing from the second terminal side to the first terminal side; and a switching element for capacitor charging that is turned ON in synchronization with a command signal that turns the upper arm switching element ON.
