When an application requires changes in motor speeds to meet its objectives, a variable frequency drive (VFD) is often the first thing that comes to mind. This is for good reason—VFDs are typically ...

出力の制御をする際にPWM制御が良く使われます。 PWM制御について、概要を紹介します。 PWM制御とは Pulse Width Modulation：パルス幅変調 パルス信号の「ON」と「OFF」の比率（デューティ比）を変えることで、出力制御方式です。 モータとスイッチを例にすると ...

What is duty cycle? Duty cycle is defined by the percentage of high voltage duration in a complete digital pulse. If the duty cycle is 50%, then it will remain on for exact half the duration of the ...

Pulse Width Modulation (PWM) is a basic concept that is employed in many areas of electronics. PWM is a simple averaging method that is used in everything from microwave power percentages to LED ...

What is pulse width modulation? Pulse width modulation (PWM) is a powerful digital technique for controlling analog circuits with a microprocessor’s digital outputs. PWM is employed in a wide variety ...
