Abstract
本発明の課題は、負荷の作動に必要な電流に応じて、発電部からの出力と蓄電部からの出力とを協調的に働かせる電源装置であって、発電部からの出力電流を一定に保ちつつ負荷の要求する電流値に対応できる電源装置を提供すること、さらに、蓄電部への充電を安全に行うことができる電源装置を提供することである。
【解決手段】
本発明は、発電部からの出力を電流変換部により定電流制御し、蓄電部の充放電を蓄電部充電部により制御することにより、発電部からの出力電流を一定に保ちつつ負荷の要求する電流値が大きい場合でも、発電部からの出力と蓄電部からの出力とを協調的に働かせることで対応することができる。また、蓄電部の充放電の制御を簡単な装置で行うことができる。
