Latest Patents

Chausse's latest patents include a method for transitioning between multiple modes of inverter control in a load. This invention involves a load side converter or inverter in a load commutated inverter motor drive, which is designed to operate in at least four modes to efficiently bring an AC motor load, particularly a synchronous motor, up to speed. The first mode is an idle state, where the converter thyristors remain non-conducting until activated for normal operation. The second mode is an initial start-up phase that does not rely on prior knowledge of the rotor's position, utilizing a fixed low-frequency firing signal to sequentially gate the thyristors. The third mode synchronizes the inverter frequency to the rotor by sensing pseudo-flux waveforms until a certain speed is achieved, leading to a self-commutation mode that employs a phase lock loop operation.

Another significant patent involves a method and apparatus for generating signals that represent motor flux. This invention generates flux signals based on the voltages and currents supplied to the motor. By sensing motor phase voltages and currents, the system develops signals that represent the direct and quadrature components of motor voltage and current, which are essential for effective motor control.
