摘要： In a synchronous machine starting device, a timing detection unit outputs a first position signal indicating a timing at which a value of an armature voltage passes a prescribed reference level. A feedback operation unit calculates an error of an estimated phase based on the estimated phase, an estimated rotational speed of a rotor, an armature voltage, and an armature current, updates the estimated phase and the estimated rotational speed based on the calculated phase error, and outputs a second position signal indicating the updated estimated phase. A frequency detection unit detects a current rotational speed of the rotor based on the first position signal, as an initial value of the estimated rotational speed. A selector circuit selects the first position signal and the second position signal in this order, and outputs a selected position signal to the power conversion control unit.
