Modular wireless charging transmitter assembly system

A modular wireless charging transmitter assembly system, the system comprising:

• an electronics module comprising:
• a module input power interface configured to receive direct current (DC) power,
• DC-to-AC converter circuitry configured to convert the DC power to alternating current (AC) power, and
• an output power interface having a first set of output pins and at least a second set of output pins, wherein AC power is provided to the first set of output pins in response to a first type of coil module being connected to the electronics module, and wherein AC power is provided to both the first and second set of output pins in response to a second type of coil module being connected to the electronics module;
• one of the first type of coil module or the second type of coil module, each coil module having a coil input interface configured to connect to the output power interface to receive AC power from the electronics module;
• and
• a fan configured to receive power from the electronics module.

A modular wireless charging system configured to provide power to one of a plurality of different types of coil modules utilized for wireless charging of a wireless charging receiver, the modular wireless charging system comprising:

• a housing body including:
• a top surface for receiving one of a plurality of different types of coil modules, and
• at least one cooling duct extending through the housing body;
• an electronics module that includes input terminals for receiving direct current (DC) power and a plurality of output terminals for selectively providing alternating current (AC) power to one or more of the plurality of output terminals based on a type of coil module connected to the electronics module via the top surface of the housing body, wherein AC power delivered to the coil module provides wireless charging of electronic devices;
• and
• at least one coil module having a bottom surface configured to be placed on the top surface of the housing body and having at least one coil configured to receive AC power from the electronics module,
• wherein the at least one cooling duct extends through the housing body from the bottom surface of the coil module to the top surface of the housing body.
