近年,永久磁石の高性能化に伴い,高効率のPMモータが様々な分野で利用されるようになってきた。PMモータのトルク制御には,回転子位置に応じた電流制御が必要で,そのため,通常はエンコーダやレゾルバなどの位置センサが用いられる。一方,位置センサが除去できれば,モータの小形化,軽量化,低価格化が実現され,耐環境性,信頼性も改善されるので,位置センサレス制御が望まれている。本稿では,PMモータの位置センサレス制御の演算に用いられるd,q軸インダクタンスの測定法について述べる。

An interior permanent magnet (IPM) motor drive system which has regenerating capability augmented by electric double-layer capacitors (EDLCs) is proposed. In the proposed system, EDLCs are arranged in series with batteries so that a lesser number of the EDLCs and batteries will be required. The proposed system has two bi-directional voltage boosters: one is for both the batteries and EDLCs to control the dc-link voltage of a PWM inverter and the other is for only the EDLCs and is used to control the energy flow from and to the EDLCs.<br>In this paper, a strategy to control the energy flow to and from the EDLCs is explained and its effectiveness is confirmed by simulation and experimental results. Furthermore, the efficiencies of the voltage booster, inverter, PM motor, and whole system are measured for the system with the basic configuration, i.e., which consists of only one bi-directional voltage booster and PWM inverter. Then, the steady-state characteristics are determined. Finally, the efficiency of the voltage boosters in the proposed system is determined, and the advantage of the proposed PM motor drive system is discussed.

The direct ac/ac converters have been investigated in the last two decades because they had no dc-link component for large energy storage. In, Japan, 10kVA-40kVA matrix converters were developed in 2005. The direct ac/ac converters are classified into two main categories, namely, the matrix converters and the direct ac/ac converters with dc Link. And various control strategies for them have already been proposed. This paper discusses and summarizes main circuits, control strategies, overvoltage protection, and ride-through capability of the direct ac/ac converters.
