TL;DR: In this article, the authors proposed a synchronous motor driving device with rectangular wave excitation in which any excitation width between 120° and 180° inclusive is selectable and sine wave excitations can be accomplished by one piece of circuitry, and the excitation wave form can be changed in a very short time according to driving conditions (high-efficiency driving conditions, low-noise driving conditions) required for a motor to be driven.

TL;DR: In this article, a noncontact transmission device that achieves power transmission and data communication by a pair of coils so as to achieve the cost reduction is presented. But the authors do not consider the effect of the power received from the receiving part on the power transmitted from the transmitting part.

TL;DR: In this paper, the authors proposed an inverter device capable of detecting instantaneous current of each phase of a motor even with a current detecting means as only one circuit on DC input side.

TL;DR: In this article, the authors propose a power supply circuit that converts an AC voltage supplied from an external power supply 35 into a DC voltage, and stores the data to be transmitted/received.

TL;DR: In this article, an environment control system 100 manages and controls control conditions of a lighting system 2 and an air conditioning system 3 capable of individually controlling environments of a plurality of regions in the living room space.
