PROBLEM TO BE SOLVED: To achieve a parallel PAM (Pulse Amplitude Modulation) control method and a simple PAM control method by one kind of substrate.SOLUTION: A circuit board comprises: a converter circuit which includes a first wiring pattern 11a for serially connecting a first inductance L1, a first diode D1 and a second wiring pattern for serially connecting a second inductance L2 and a second diode D2, switching elements IGBT1, IGBT2 connected to the first wiring pattern 11a and the second wiring pattern 11b and a control part 12; and ground patterns GND connected by a common land. The first wiring pattern 11a and the second wiring pattern 11b are formed to have substantially the same width. The first wiring pattern 11a is divided so as to leave predetermined room and the second wiring pattern 11b is divided so as to leave predetermined room and a ground pattern GND is arranged on a region of each predetermined room left by division. The divided first wiring patterns 11a are connected with each other and the divided second wiring patterns are connected with each other by jumper lines 13a, 13b, respectively. 【課題】１種類の基板で並列ＰＡＭ制御方式と簡易ＰＡＭ制御方式を実現すること。【解決手段】コンバータ回路は、第１インダクタンスＬ１と第１ダイオートＤ１とを直列に接続する第１配線パターン１１ａと、第２インダクタンスＬ２と第２ダイオードＤ２とを直列に接続するための第２配線パターン１１ｂと、それらに接続されるスイッチング素子ＩＧＢＴ１，ＩＧＢＴ２と、制御部１２とによって構成され、グランドパターンＧＮＤは共通のランドで接続され、第１配線パターン１１ａ及び第２配線パターン１１ｂは、略同じ幅に形成され、第１配線パターン１１ａが所定間隔空くよう分割され、第２配線パターン１１ｂが所定間隔空くよう分割され、それぞれ分割された所定間隔の領域にグランドパターンＧＮＤが配置され、分割された第１配線パターン１１ａ同士と、第２配線パターン１１ｂ同士がジャンパー線１３ａ，１３ｂで接続される。【選択図】図２
