Description
なる。
図4は、この出願の発明の一実施形態を示したものである。
力を供給する。
図5は、この出願の発明の別の一実施形態を示したものである。
図6は、この出願の発明のさらに別の一実施形態を示したものである。
図7および図8は、各々、この出願の発明の参考実施形態を示したものである。これら図7および図8に示した参考実施形態では、蓄電池Bと双方向DC−DCコンバータConvを直結することにより逆潮流が可能なものとなっている。現在、国内の売電契約の中では夜間・深夜電力を逆潮流させることは許容されていないが、風力発電・太陽光発電については逆潮流が認められており、燃料電池発電時の逆潮流については不明であるが、純技術的観点から見ると逆潮流はすべて可能になる。
交流専用負荷Lacおよび蓄電池B系を完全に絶縁し、それぞれの電圧値にも整合する巻数比において、高周波変圧器HFTはすべて正弦波商用交流周波数でのエンベロープ変調動作が可能となり、負荷はすべて従来の交流専用負荷Lacが使用可能となる。
[参考例]
巻線電子変圧器4・三巻線電子変圧器5を通して商用交流電源側へ逆潮流を行うことが可能になる。なお、この場合、停電時のインバータ動作用発振器を内蔵することは言うまでもない。
