Latest Patents
One of Valentin Costan's latest patents is titled "Electrical defect detection in a generator." This innovative method involves monitoring and detecting defects in a doubly-fed asynchronous machine, which includes both a stator and a rotor. The method utilizes computer means to receive current and voltage measurements of the stator, along with the relative rotation speed between the stator and rotor. It deduces a stator power function over time and performs harmonic analysis using wavelet transforms. By comparing the resulting harmonic representation to a reference, the method effectively identifies potential defects in the machine.
Another significant patent is the "System for converting at least one electrical input direct current into an electrical polyphase output alternating current." This system comprises multiple phases and output terminals, utilizing polyphase inverters connected in parallel. Each inverter converts the input direct current into an intermediate alternating current, which is then processed through electromagnetic coupling coils and magnetic cores. This innovative design generates common mode fluxes of opposite directions, enhancing the efficiency of the electrical output.
