Latest Patents

One of his latest patents is a controller for a three-phase brushless D.C. motor. This controller features a full bridge circuit and an electronic control unit (ECU). The full bridge circuit consists of three branches, each equipped with switches connected to the motor windings. The switches are activated by signals from the ECU, which are arranged in two sets of three signals, offset by 180 electrical degrees. Each set's drive signals are further offset by 120 electrical degrees, incorporating an active portion that alternates with an inactive portion. This active portion includes an initial interval of pulsed activation, an intermediate interval of continuous activation, and a final interval of pulsed activation. Notably, the active portion of the drive signals exceeds 120 electrical degrees, with overlapping intervals of pulsed activation.

Another significant patent is a system for controlling the speed of an electric fan. This system includes a driving circuit for the motor of the electric fan, which is connected to the electrical system of a motor vehicle. It features multiple controlled electronic switches and an electronic control unit designed to manage the driving circuit. This control unit enables the motor to operate at a variable average current, producing the desired speed of rotation based on a predetermined function. Additionally, the control unit can store a threshold for rotation speed, allowing it to implement electrical braking when the motor exceeds this threshold.
