Description
この実施形態によれば、パルス群の1つのNパルスが常に入力電圧のゼロクロス点Pを跨って生成されるように、ON−OFFパルスを出力するようにした。したがって、PAM波形の位相がずれても、常にOFFパルスから出力すればよいことになる。つまり、PAM波形の位相がずれることで、ONパルスがゼロクロス点Pから外れてOFFパルスがゼロクロス点Pを跨った場合、ONパルスから出力しなければならなくなる。そうすると、OFFパルスから出力する出力タイミングと、ONパルスから出力する出力タイミングの2つのタイミングが必要になるが、本実施形態の場合には1つの出力タイミングで足りる。このように、複数の出力タイミングを用意しなくてもよいため、PAM制御を簡単化することができ、制御性を向上させることができる。
上述した実施形態については以下のような構成としてもよい。
12 ダイオードブリッジ回路(整流回路)
15 マイコン(PAM制御部)
5a ゼロクロス検出部
5b PAM波形出力部
5c タイマー部
S スイッチング素子
D1〜D4 ダイオード
C1,C2 コンデンサ
