PWM-H-Bridge
About the PWM-H-Bridge PCB
PWM-H-Bridge is an open source PCB design by NealEhardt, published on GitHub. It is a 2-layer board measuring 70 × 71 mm, with 35 components from 17 distinct parts.
Other key parts include the IR2113, TLC555, 4049 and L7805. By type, the board carries 12 capacitors, 8 resistors, 5 ICs, 4 transistors, 3 connectors and 2 diodes.
It belongs with the iot & wireless designs in this gallery.
From the project
PCB for wireless power transmission
This repository includes the KiCad project and Gerber files for a PCB that converts DC➡AC to transmitt wireless power through a coil. It generates a PWM signal in the KHz range to control an H-bridge. Frequency is adjustible with a knob.
This repo contains rev. 2 which is nearly identical to the above image, except I fixed an issue where the diodes were reversed.
