Abstract: In a pulse edge detection circuit, a measurement circuit has a comparator provided therein which compares a voltage with a reference voltage and outputs a pulse signal. An RSFF puts a signal in a high level at a timing at which detecting a rise edge due to a change of the pulse signal to the high level. In such manner, a set signal of an RSFF becomes inactive and a reset signal of the RSFF becomes active, and a fall edge of the pulse signal becomes detectable. When a fall edge is generated due to a change of the pulse signal from the high level to the low level, the set signal of the RSFF becomes active, and a signal becomes high level.

Abstract: The power conversion device includes a plurality of semiconductor modules, each having a main body section including a switching element therein. In a module unit, a positive module and a negative module are disposed such that main surfaces of the respective main body sections oppose each other. A positive terminal, a first intermediate terminal, a negative terminal, and a second intermediate terminal project in a Z direction perpendicular to X direction in which the positive module and the negative module oppose each other. A first vector V1 from the positive terminal towards the first intermediate terminal and a second vector V2 from the second intermediate terminal towards the negative terminal are configured such that these vector components V12 and V22 in a Y direction perpendicular to both the X and Z directions are opposite to each other.
