  "textContent": "A desired effective voltage can be ensured with certainty in a preheating control. An operation control part 52 reads a correction value c with respect to a battery voltage Vb at the time of performing correction based on preliminarily stored correlation between a battery voltage Vb of a vehicle-use battery and a correction value c (S104, S106), and compensates for lowering of an effective value of a pulse voltage by adding a correction value c to a duty ratio calculated by a predetermined arithmetic expression thus ensuring a desired effective voltage with certainty in a preheating control.",
