ST STDES-50W2CWBC - Overview; Figure 1. STDES-50 W2 CWBC Reference Design; Figure 2. Block Diagram of a Typical Power Transfer System

1 Overview
Wireless power transfer is a fast-growing technology in many application fields. The wireless power can be from
several mW (for example, in the medical field) to tens of kW (for example, an electronic vehicle).
There are multiple physical mechanisms to address the wireless power, such as magnetic inductance, magnetic
resonance, capacitive coupling, radio frequency, laser charging, etc.
The most popular mechanism is the magnetic inductive that follows the Qi standard defined by the Wireless
Power Consortium (WPC).
The STDES-50W2CWBC dual-coil reference design follows the WPC MP-A2 topology.
