摘要： The DC-DC converter can calculate an input voltage without being influenced by a commutation time period of a primary-side current of a transformer. The DC-DC converter includes a transformer that has a primary and secondary winding, a switching circuit that is connected to the primary winding of the transformer to perform input voltage switching, a drive circuit that drives the switching circuit, a rectifier circuit that rectifies an AC voltage generated in the secondary winding of the transformer according to the switching operation of the switching circuit, and a controller that evaluates a value of the input voltage and performs predetermined processing based on the value of the input voltage. The controller detects a pulse signal emerging on an input side or an output side of the rectifier circuit, calculates a duty of the pulse signal, and evaluates the value of the input voltage based on the calculated duty.

摘要： Charge efficiency of normal charge is improved without restricting an operation of a low-voltage load of an electric vehicle during the normal charge. During a charge of a high-voltage battery of a vehicle, when a determination of the normal charge is made, and when a determination that a mode switching target load is not operated is made, power saving mode transition processing is performed. Therefore, an operating mode of a DC-DC converter, which steps down a voltage at the high-voltage battery and supplies the stepped-down voltage to a low-voltage battery and a low-voltage load, is set to a power saving mode in which consumption power is reduced compared with a normal mode. When a determination that a start-up manipulation of the mode switching target load is performed is made, the operating mode of the DC-DC converter is changed to the normal mode.
