2021年度の研究では，申請書において当初より提案しているワイヤレス給電システムにおいて，製造誤差や磁気干渉に伴う共振周波数のばらつきや変化によらず安定的な送電能力を実現するための具体的な制御方法の要件を理論的に解析し，その妥当性を実験的に実証した。理論解析では，ワイヤレス給電システムの回路動作において，電力を担う基本波成分の電圧・電流波形の振る舞いに着目し，基本波成分のみの動作を表現する等価回路モデルを構築した。この等価回路モデルの動作を分析した結果，送電器の交流電源に対して同期するように送電器のATACを位相差0°で，かつ，受電器のATACをすべて位相差90°で動作させることで共振周波数のばらつきや変化によらない送電能力が実現できることを発見した。
さらに，このように理論的に導出したATACの動作条件の妥当性を確認するため，提案するワイヤレス給電システムの実験回路を構築し，このATACの駆動条件における送電電力の特性を評価した。この実験では，製造誤差や磁気干渉に伴う共振周波数のばらつきや変化を想定し，受電器の共振周波数を敢えて最適値からずらしたときの送電電力の変化や，複数の受電器間の磁気結合を変化させたときの送電電力の変化を評価した。その結果，理論的に予想したとおり，受電器の共振周波数の変化や，受電器間の磁気結合の変化によらず一定の送電電力を得ることが確認でき，提案システムが期待通り有望であることを確認できた。 -

申請者はこれまでSiCと双璧をなす次世代パワーデバイスであるGaNパワーデバイスの連鎖的誤動作解明に取り組んできた。ディジタル的なスイッチング(ON-OFF) 動作をするGaNパワーデバイスに発生する誤動作が，実はアナログ回路におけるバルクハウゼンの発振原理に基づいており，「GaNパワーデバイスが持つ端子間寄生容量と回路配線によるドレイン，ソース，ゲートの各寄生インダクタンスによって構成する三つのLC共振要素の共振周波数の大小関係を適切に制御することで誤動作抑制が可能である」という理論を，世界に先駆けて明らかにした。これは「配線インダクタンスを単に小さくするのではなく，GaNパワーデバイス自身が持つ寄生容量にあわせて配線インダクタンスを適切に調整することで連鎖的誤動作抑制が可能」なことを意味している。この理論はまだ普及が進んでいないGaNパワーデバイスに留まらず，SiCパワーデバイスにも適用できると考えている。そこで，2019年度は，SiCパワーデバイスのターンオフ直後の単発誤動作に着目してその出現条件を実験的に明らかにした。
2020年度は，前年度に明らかになったSiCパワーデバイスのターンオフ直後の単発誤転弧の出現条件から，(1)誤転弧発生メカニズムの解明，(2)その抑制理論の構築を行った。さらに，(2)の検証を行うべく，抑制理論に一部基づいて設計した三相インバータ回路を試作した。 -

Ultra-high-speed, low on-resistance GaN-FETs are attracting attention as next-generation power semiconductor devices, and are becoming essential for the development of small-sized, high-efficiency power supplies. However, since high speed operation is possible, there is a concern about increase in noise. Since the GaN-FET has a low on-off threshold voltage, it is prone to malfunction. Since this malfunction may destroy the GaN-FET itself, it is a major obstacle to the industrial application of the GaN-FET.
In this research, we focused on the chain-like malfunction peculiar to GaN-FET, clarified the relationship between the malfunction mechanism and the circuit parasitic inductance, and developed the circuit wiring design method that can make full use of the high-speed switching characteristics possessed by GaN. -

This research deals with a Fuel Cell(FC) generation system with a reformer for home appliances. The proposed FC generation system is with an EDLC. The EDLC stores the power generated from FC when the load in a house is changed from heavy to light conditions. The EDLC supplies power to the load when the load is changed from light to heavy conditions. So the proposed FC generation system can compensate the oversupply and shortage power from the FC. A current balancer operation is added to the power conditioner. This balancer operation improves the efficiency of the pole mounted distribution transformer. A variable capacity capacitor simulator with an inner resistor is also proposed. A proto type laboratory model is constructed and tested. Detail evaluations of the constructed mode and economical review are an important issue for further study.

The summary of this research results is as follows:
1. Development of the FC simulator with a reformer The FC simulator with a reformer has been constructed using a controllable dc power supply, and tested to demonstrate the validity of the constructed FC simulator.
2. Development of the grid-connectable inverter for the FC The grid-connectable inverter for the FC has been constructed with a DSP-based control system, where the inverter acts as a power line conditioner. Thus the balanced and sinusoidal source currents are obtained generating the dc power by the FC.
3. Confirmation of the surplus power in the home uses of the FC generation system We have demonstrated that the surplus and deficit power exits when the consumed power in a home is suddenly changed. Suppressing the surplus power is needed because the injection of the power generated by the FC generation system to power systems is not permitted by Japanese low. Thus the moment of inertia of the fly-wheel generator is decided.
4. Construction of the fly-wheel generator The fly-wheel simulator with the dc motor drive system has been constructed on PSIM software, where the do motor drive system acts as a fly-wheel. The moment of inertia is controllable. Thus the constructed fly-wheel simulator is useful for various home uses.
5. Construction of a FC generation system for home uses A FC generation system with a fly-wheel generator simulator has been constructed considering a typical Japanese home. In home uses of the FC generation system, the load conditions are suddenly changed. So the surplus and deficit power exists as described the above. We have demonstrated that the surplus and deficit power generated by the FC generation system are perfectly suppressed by the fly-wheel generator by digital computer simulation.
6. Development of a EDLC simulator According to the development plan of the DOE, the response time of a reformer will be less than 2s by 2010. This means that an EDLC can be used to suppress the surplus and deficit power. Thus we have developed an EDLC simulator for home uses. -

The three-phase PWM inverters and three phase PWM rectifier have been designed so as to operate on the basis of the high frequency switching sinewave pulse modulation scheme more than 16 kHz or more. The performance enhancement relating waveform quality and quick response and downsizing realization of three- phase PWM power converter circuits and systems mentioned above are strongly required for high- frequency switching sinewave pulse modulation and control implementation. In general, the switching power losses of the power semiconductor devices and power modules, and switching voltage and current surge related electromagnetic noise generated by a high dv/dt and di/dt tend to increase in those of three-phase hard switching sinewave PWM inverters and rectifiers.
Thus, soft switching sinewave PWM power conversion circuit and system techniques operating under soft commutation conditions of zero voltage switching transition and zero current switching transition are more indispensable for the concrete realization of the high efficiency in power conversion processing and reduced switching noises even in high frequency switching sinewave PWM strategy because of reduced dv/dt and di/dt electrical stresses and switching power losses in power semiconductor devices..
This paper presents the simulation and experimental evaluations and discussions of the three-phase voltage source type soft switching PWM inverter using the three auxiliary resonant commutation snubbers, which can be turned on and turned off with zero current and zero voltage hybrid switching as the perfect soft switching. The operating principle of this ZCS & ZVS type auxiliary resonant commutation snubber circuit is described and evaluated herein. In addition to this, its optimum circuit parameters are determined from a simulation point of view. Finally, the operating performances of this resonant snubber assisted three-phase voltage source type soft switching sinewave PWM inverter are evaluated and discussed on the basis of the 3kW experimental setup.
