WIRELESS POWER TRANSFER PROJECT

Abstract

The project uses two copper coil windings, one as primary and another one as secondary. The primary coil is center tapped and connected to amplifier BD139 with filters to transmit the power efficiently. Secondary coil is directly connected to a series of LED’s Based on the wireless gap between both coils, power will be transmitted wirelessly to the other coil which will glow the LED’s

Circuit Diagram

Instructions

·         Make both the copper coils(primary & secondary) stand and face each other (or) make one coil overlap other.

·         Connect the battery

·         As you keep moving the secondary coil close to the primary coil yhe LED’s will  glow bright and vice versa
