Latest Patents

Sergio holds a patent for a resonant converter, which includes a full-bridge switch circuit, a resonant circuit, a transformer, a rectifier circuit, a current sensor, and a controller. The full-bridge switch circuit comprises switches that facilitate the operation of the converter. The resonant circuit is connected to the full-bridge switch circuit and features a resonant inductor. The transformer is designed with primary and secondary windings, with the primary winding linked to the resonant circuit. The rectifier circuit is connected to the secondary winding, while the current sensor monitors the current flowing through the resonant inductor. When this current passes through the current sensor, it generates a current differential signal. The controller then performs double integration on this signal to acquire an electric charge signal, which is used to control the operation of the switches based on the electric charge signal and the input and output voltages of the resonant converter. This innovative design enhances the efficiency and performance of power conversion systems.
