SEMICONDUCTOR ELEMENT CONTROLLER AND IN-VEHICLE ELECTRIC SYSTEM |
摘要 |
<p>A semiconductor element control device that controls a semiconductor element that performs switching operation for converting DC power into AC power, or AC power into DC power, includes: a drive unit that outputs a drive signal for controlling the switching operation of the semiconductor element to a terminal of the semiconductor element; a short-circuit detection unit that detects short-circuit of the semiconductor element on the basis of the voltage at the terminal, and outputs a short-circuit detection signal; and a drive interruption unit that interrupts current flowing in the semiconductor element on the basis of the short-circuit detection signal output from the short-circuit detection unit.</p> |
