CircuitForge

Introduction

CircuitForge is an interactive online PWM circuit builder and simulator. Drag and drop PWM controllers (Arduino, ESP32, STM32), power components (MOSFET, IGBT, transistor), passive elements (resistor, capacitor, inductor), and protection devices (fuse, TVS diode, current limiter). Run real-time circuit simulation with frequency, duty cycle, peak current, thermal analysis, efficiency metrics, and safety warnings — all in the browser.
