Qi® Wireless Charger and Receiver | High-Wattage Wireless Charger and Receiver
Wireless charging works by transferring energy from the charger to a receiver via electromagnetic induction. The charger uses an induction coil to create an alternating electromagnetic field, which the receiver coil converts back into electricity to be fed into a battery or directly to an application. Typically, the charger and receiver should be close and correctly aligned over the top of each other, although a set orientation is normally not necessary.
Developed by the Wireless Power Consortium, the Qi wireless charging standard defines wireless power transfer using inductive charging over distances of up to 4 cm. A Qi-based wireless charging system uses resonant inductive coupling to enable a charging pad to transfer power to a compatible device when it is placed on top of the pad.
Our dsPIC® Digital Signal Controllers (DSCs), with their multiple Pulse-Width Modulators (PWMs), high-speed Analog-to-Digital Converters (ADCs) and programmable core, are very effective in optimizing wireless charging solutions. To help jump start your development, we offer reference designs for 15W single- and multi-coil Qi-compliant transmitters.
For applications that may require higher wattage, we also offer the 200W/300W Wireless Power Reference Design that implements a proprietary protocol that is ideal for applications such as power tools, robotic vacuums, industrial slip rings, small electric vehicles and drones.
Wireless Power: Three-Coil Transmitter
Qi® Wireless Power Micro-Receiver Reference Design
The Wireless Power Micro-Receiver allows you to quickly add wireless charging functionality to your project without having to deal with complex specific protocols or state machines. This receiver is implemented using a general-purpose 8-bit microcontroller and is a flexible, low-cost alternative to the common wireless charging solutions based on ASICs. The receiver is compatible with the Qi 1.1 (5W) standard and can be used in conjunction with any Qi 1.1-compatible wireless charging transmitters (all Qi 1.2 or higher compliant base stations are also backwards compatible with Qi 1.1).
Qi® Wireless Charging LED Lantern Reference Design
Our Qi wireless LED lantern is a lighting solution with wireless charging capabilities. It is able to draw up to 5W from a base station and charge a Li-Ion battery at 1A.
Qi® Wireless 15W Receiver Reference Design
This advanced wireless receiver is compatible with Qi 1.2 base stations and is able to draw up to 15W of power that can be used to run portable devices or charge batteries. You can quickly incorporate this receiver into your designs without dealing with the Qi protocol state machine and communication.
15W Multi-Coil Wireless Power Transmitter
The three coil wireless power transmitter is based on the dsPIC33CH128MP506 DSC and implements a fixed-frequency power control topology. The front-end buck-boost control is managed by the dsPIC33CH DSC. The transmitter includes CAN for ease of integration into the automotive environment. The transmitter also enables the implementation of Near Field Communication (NFC).
15W Wireless Power Demonstration Board
The 15W Wireless Power Transmitter Board, based on the dsPIC33 DSC, is compatible with Qi medium-power receivers. The development board enables a system efficiency of about 80% at full load and includes LEDs to indicate status and power level.
200W Wireless Power Reference Design
The 200W Wireless Power Reference Design is based on custom Microchip microcontrollers. It implements a proprietary protocol developed from several granted U.S. patents in communication, power control and Foreign Object Detection (FOD).

Digital Power Starter Kit Demonstration – MASTERs Conference 2015
Digital Power Starter Kit Demonstration – MASTERs Conference 2015
This is a Live Update demonstration of the power supply firmware using Microchip’s new dsPIC33EP ‘GS’ devices. These devices contain two flash partitions such that programming of the inactive partition can occur without stalling the CPU which then leads to continuous regulation of the power supply (i.e. no down time to update PSU firmware). The demonstration shows an extreme case where the compensator is being changed from an poorly designed 2P2Z compensator to a properly designed 3P3Z compensator.
