Latest Patents

Dongmin Liu holds a patent for an "Integrated tri-state electromagnetic interference filter and line conditioning module." This patent describes systems, methods, and articles of a passive EMI filter integrated with an active boost converter for low-side line transients and/or an active clipper for high-side line transients. During steady-state operation, the active circuitry is disabled, allowing the circuit to function as a passive EMI filter. The inductive and capacitive components used in the passive EMI filter during steady-state operation may serve a dual role, becoming part of a boost converter when input voltage is below a low-line steady-state. In some variations, these components may also become part of a transient clipper when the input voltage exceeds a high-line steady-state level. The transient clipper can be implemented as a linear pass element or as a switch-mode converter, such as a buck converter. Dongmin Liu has 1 patent to his name.
