Thus, multi-level or hybrid converters can be a solution to reduce the size of passive devices and to achieve a higher efficiency at high input voltages compared with 2-L converters [1-4]. Another trend for mobile applications is wireless power sharing, which allows one mobile device to charge another device (e.g., smart watch, phone, or earbuds). If a travel adapter (T.A) is attached to the mobile device, wireless power sharing can allow two devices to be charged at the same time. To support this feature, the dual-input bi-directional 3-level
