Single PFC and Interleaved PFC In basic PFC operation, a sawtooth-wave current is passed through an inductor, and by executing control such that the current average value is sinusoidal, the shift in the voltage and current phases is corrected.
The Basics of Class D Amplifiers While there are a variety of modulator topologies used in modern Class D amplifiers, the most basic topology utilizes pulse-width modulation(PWM) with a triangle-wave(or sawtooth) oscillator.

Design concept for a basic triangular-wave generator. Figure 2.
内部信号は正弦波や三角波,のこぎり波,矩形波などで、編集も可。
Internal Signal: Sine wave, Triangle, Sawtooth, Square and so on.
はじめに三角波形の直線性によって、三角波ジェネレータは多くの「掃引」回路や試験装置で役立ちます。
Introduction The linearity of triangular waveforms makes triangular wave generators useful in many"sweep" circuits and test equipment.
Wave4種類の波形(サイン波、三角波、のこぎり波、矩形波)から選択できます。
Wave Allows you to choose between the waveforms sine, triangle, saw, and square.
Some carrier waveforms have intrinsic second order discontinuities(triangle), first order discontinuities(rectangle), or both sawtooth.
ILで表されるインダクタ電流の三角波のピークは、インダクタンスLが大きくなると小さくなります。
The peaks of the sawtooth-wave inductor current, represented by ΔIL, become smaller as the magnitude of the inductance L is increased.
ESRによっては、オームの法則の通りそのまま三角波の電圧になり容量によっては時定数を持ちます。
Depending on the ESR the capacitor current directly becomes a triangular wave voltage according to Ohm's Law, and based on its capacitance it acquires a time constant.
