Latest Patents

One of his latest patents is a hybrid DC-DC converter that integrates an LLC converter and a full-bridge converter. This hybrid DC-DC converter features a pair of transformers that magnetically couple the primary side to the secondary side. It includes a full-bridge converter with four switches forming a full-bridge inverter circuit and a first transformer. Additionally, it incorporates an LLC resonant converter with a resonant inductor, a resonant capacitor, and a second transformer, which together create an LLC resonant circuit. The outputs of both the full-bridge converter and the LLC resonant converter are connected in series at the secondary side.

Another notable patent involves an apparatus and method for controlling multiple power converting modules, as well as analyzing power quantity imbalances. This technology improves the management of power quantities processed by several power converting modules. It detects relative power quantities through a common circuit element at the input or output terminal shared by the modules, rather than relying on individual current or voltage sensors. The control values for each module can be adjusted based on the detected relative power quantities, providing users with easily identifiable output information.
