DC と AC の違いの本質は、AC が、負荷に影響を与える方向の変化という点で、2 セットの交互の DC と見なすことができることです。これは、異なる場所での 2 セットの DC のベクトル和として理解できます。期間。十分に短い時間の間、交流は一方向の一連の直流として理解できます。
私たちは電気を使うと、電気の影響を目にすることになります。抵抗性負荷の場合、これは熱効果であるため、AC と DC の最終的な効果はまったく同じで、どちらも加熱されますが、AC の大きさは通常変化するため、DC 効果と同等の「rms」を取得します。しかし、誘導性負荷と容量性負荷の場合、AC には方向があり、スムーズに「通過」できます。それらは DC では達成できません。また、AC は変化する磁場を生成でき、変化する磁場は変化する電場を生成できるため、エネルギーは非常に簡単に変換および伝送されます。したがって、交流はより広く使用されています。たとえば、変圧器は単純に電圧の値を変更できますが、直流は直接変更できません。たとえば、無線伝送では、変化する磁場を生成するためにこれらの交流電圧も必要ですが、一方向では一部の直流電流では要件を満たすことができません。
直流は一方向なので、比較的使いやすいです。高い状態と低い状態の 2 つの状態に簡単に分けることができます。このようにして、バイナリ 0 と 1 の物理状態を簡単に実現できます。したがって、チップの論理制御にはもちろん直流が必要であり、交流は複雑すぎます。
一部の電源の変更でも、周波数変換器やスイッチング電源のように、最初に AC を DC に変換し、次に電圧を安定させて簡素化し、チョッピングによって別の AC を反転するのが一般的です。
