ドレミファインバータの改良版を作りました。改良前の記事↓

スイッチング素子はIGBTを使用しています。ゲートドライブ回路は基板制作時にフットプリントのミスがあったため、パターンカットして使いました。

メインコントローラはRaspberry-Pi-Picoを使用しています。クロック周波数はオーバークロックさせて250MHzで使っています。メインコントローラに可変抵抗をつないで、その値をもとに加速度を制御しています。

GitHubにKiCad回路図とソースコードを載せています。

※回路の保証はありませんので、自己責任で製作してください。AC100Vを扱うため、誤った扱いをすると危険です。

上記コードで、以下の2つは加速用と減速用です。

パラメータは以下のような構造になっています。

{モーターの周波数（開始）, 同期モードの場合は0、非同期モードの場合は1, 同期3パルスモードのときのみ1、それ以外は0, 同期モードのパルス数または非同期モードのパルス数（開始）, 同期モードのパルス数または非同期モードのパルス数（終了）, ランダム変調の場合は0～1までの小数数値、それ以外は0, 高周波重畳モードの場合は1以上の整数、それ以外は0}

同期モード、非同期モードについて

同期モードはモーターの回転数が上がると、それに同期して周波数が上がるように聞こえるパルスモードです。1周期あたりのパルス数は同じになります。
非同期モードはモーターの回転数に関係なく、一定の周波数が聞こえるパルスモードです。1周期当たりのパルス数は異なります。

ランダム変調について

インバータ音でノイジーな音がするものがありますが、それにランダム変調が使用されています。

高周波重畳について

主にPMSMのモーターで使用されている方式です。モーターの回転位置検出をするため、この方式になっています。
