Abstract: This letter analyzes the proposed variable-sawtooth-based PWM controller for the ac-coupled envelope tracking (ET) supply modulator (SM). The ET SM includes a linear amplifier and a ...
There’s been interest recently here in the land of Design Ideas (DIs) in a family of simple interface circuits for pulse width modulation (PWM) control of generic voltage regulators (both linear and ...
A new reference design developed by ROHM Semiconductor uses a single microcontroller (MCU) to control both sides of the AC-DC power supply — the power-factor-correction (PFC) AC-DC converter stage and ...
It features adjustable maximum speed, minimum speed, current limit, I.R. compensation and acceleration, plus a quiet operating frequency of 18kHz. Aug.5, 2025 – Dart Controls introduces the 65E, a ...
“Two halves make a whole” is a very old and often true maxim. For example, it’s almost always true when said about AC phase angle power control. You rarely want significant alternating half-cycle ...
In 2008, I acquired my first camera and fell in love with producing visual experiences! I was learning to edit by myself by watching Videocopilot and YouTube tutorials. I spent a semester and a half ...

Abstract: Many commercial controller implementations for dc-dc converters are based on pulse-width modulation (PWM) and small-signal analysis. Increasing switching frequencies, linked in part to wide ...
