図1は、本実施形態の高周波電源装置の構成例を示す回路図である。この高周波電源装置は、例えば誘導結合プラズマ(ICP)発光分析装置などの分析装置に適用可能であり、直流電源1、バイパスコンデンサ2、スイッチング回路3、インピーダンス変換回路4及びLC共振回路5などを備えた自励発振方式の高周波電源装置である。
図2は、本実施形態のトランス6の内部構成について説明するための概略図である。トランス6は、LC共振回路5に備えられた1次コイル53と、ゲート駆動回路32に備えられた2次コイル33とにより構成されている。
図3は、本実施形態のMOSFET31の周辺の構成例を示す部分平面図の一例である。また、図4は、図3のA-A断面を示す断面図である。また、図5は、図3のB-B断面を示す断面図である。
図3~5に示すように、基板10上において対を成すトランス6及び抵抗体54のそれぞれに対して、それぞれ異なる放熱器20が接触していてもよいし、図6に示すように、1つの放熱器20が対を成すトランス6及び抵抗体54の各々に接触していてもよい。なお、図6は、本実施形態のMOSFET31の周辺の構成例を示す部分平面図の他の例である。また、図6では、具体的に、MOSFET31a等のうちの2つのMOSFET31の周辺の構成を示す。
