Title: Innovations of Sang Woo Nam
Introduction
Sang Woo Nam is a prominent inventor based in Cambridge, CA, known for his significant contributions to power control technologies. With a total of five patents to his name, he has made remarkable advancements in the field of active rectifiers and power converters.
Latest Patents
One of his latest patents is titled "Reactive AFE Power Control." This invention features an active rectifier equipped with a controller that includes a feedforward component, a modulator, and a modulation index controller. The modulator generates switching control signals based on a reference to convert AC input power, effectively controlling the DC bus voltage at the DC output. The feedforward component calculates the reference using an estimated total inductance of the AC input, grid voltage, modulation index reference, and a reactive power offset signal. The modulation index controller then computes the reactive power offset signal based on the error between the modulation index reference and a feedback modulation index.
Another notable patent is "Multi-segment and Nonlinear Droop Control for Parallel Operating Active Front End Power Converters." This invention involves an active rectifier that includes first and second DC nodes, a switching circuit, and a controller. The controller computes a voltage reference based on a load signal of the DC output and a non-linear relationship between the load condition and the DC bus voltage. It generates rectifier switching control signals according to the voltage reference, enabling the switching circuit to convert AC input power and control the DC bus voltage at the DC output.
