Latest Patents

One of his latest patents is titled "Fast model predictive pulse pattern control." This invention involves a method for controlling an electrical converter by determining an error value based on the difference between an estimated output value and a reference output value. The estimated output value is derived from measurements taken within the electrical converter. The method includes comparing the error value with an error band, and if the error value exceeds this band, the converter is controlled by switching to a different control scheme. The converter is managed with a modified pre-calculated switching sequence, which is based on the actual state of the converter. This sequence includes a series of switching transitions, which are adjusted to minimize the error value.

Another significant patent is for a "Converter for a battery charging station." This modular converter features at least two charging modules connected in parallel. Each module is designed to generate an output current for charging a battery. Each charging module is equipped with a local controller that manages the charging process. The local controllers are capable of determining both a global charging current and the output current for their respective modules.
