    Abstract: A power conversion device includes: circuit boards; at least one engagement member configured to engage a male engagement member with a female engagement member to allow the circuit boards to be electrically connected, the male engagement member being connected to one of the circuit boards and having a substantially flat plate-shaped insertion portion, the female engagement member being connected to another of the circuit boards and having first and second clamping portions disposed to face each other, and the engagement of the engagement members being made by clamping the insertion portion by the clamping portions; a differential amplifier configured to measure a voltage across the engagement member; an arithmetic unit configured to estimate a resistance value of the engagement member based on the measured voltage; and a power conversion circuit controller configured to perform notification on condition that the estimated resistance value exceeds a resistance threshold.
