| 摘要 | A regulator device includes: a plurality of regulators that are equipped in parallel between a power input terminal and a power output terminal and converts a power inputted from the power input terminal to output to the power output terminal; a dummy load circuit that is coupled to a power output system different from a power output system to the respective power output terminal of the plurality of regulators; a selector that selects a regulator to carry out an output to the power output terminal and a regulator to carry out an output to the dummy load circuit among the plurality of regulators; and a controller that obtains conversion efficiency characteristic information representing a characteristic of power conversion efficiency relative to a current flowing in the dummy load circuit for the regulator to carry out an output to the dummy load circuit. | ||

| 主权项 | 1. A regulator device comprising: a plurality of regulators that are equipped in parallel between a power input terminal and a power output terminal and converts a power inputted from the power input terminal to output to the power output terminal, the plurality of regulators each including a conversion efficiency measurement circuit to measure a characteristic of the power conversion efficiency relative to an output current; a dummy load circuit that is coupled to a power output system different from a power output system to the respective power output terminal of the plurality of regulators; a memory that stores conversion efficiency characteristic information of the plurality of regulators, the conversion efficiency characteristic information representing a characteristic of power conversion efficiency relative to a current flowing; and a controller that reads out the conversion efficiency characteristic information from the memory and selects one of the plurality of regulators to carry out an output to the power output terminal and one of the plurality of regulators to carry out an output to the dummy load circuit among the plurality of regulators. | ||
