چکیده
Iron loss is a possible source of performance deterioration, especially for a torque regulation, in field oriented induction machine. In this paper, study on the model of an induction machine with iron losses, a flux estimation strategy, the design of direct and indirect field oriented controller, a precise torque regulation scheme and the determination of a core loss resistance are discussed. Simulation and experimental results are also included and show the effectiveness of the proposed analysis and the proposed control strategy.

NONLINEAR-CARRIER CONTROL FOR HIGH-POWER-FACTOR RECTIFIERS BASED ON FLYBACK, CUK OR SEPIC CONVERTERS - Applied Power Electronics Conference and Exposition, 1996. APEC '96.Conference Proceedings 1996.,
In this paper, nonlinear-carrier (NLC) control is proposed for high-power-factor rectifiers based on flyback, Cuk or Sepic converters operated in the continuous conduction mode. In the NLC controller, the switch duty ratio is determined by comparing a signal proportional to the integral of the switch current with a periodic nonlinear carrier waveform. The shape of the NLC waveform is determined...

Abslrad : Some practical methods --r implementing the sliding-mode control law to control the buck-type converters are introduced. The control equations are derived from the basic slidmg-mode control law to accommodate the conventional fiied-frequency pwm control method. As a result, the overall feedback control systems can be expressed under a form similar to state-feedback control where the v...
متن کاملFeedforward Ripple Cancellation for a Full-Bridge Converter - Applied Power Electronics Conference and Exposition, 2000. APEC 2000. Fifteenth Annual IEEE
AbstmctThis paper presents a feedforward ripple cancellation technique for use with a full-bridge DC-DC converter. The full-bridge is used to energize an inductive coupling that serves as an isolating connector in a battery charging system. Feedforward ripple cancellation prevents large ac currents from flowing into the battery terminals in response to unavoidable ac ripple on the inverter inpu...

Abstruct-This paper proposes a transformer assisted PWM zero voltage switching Neutral-Point-Clamped (NPC) inverter. With the assistance of a transformer assisted small rating lossless auxiliary circuit, the main switches work with zero voltage switching without suffering from any voltage/current spikes, under simple explicit control. The technique allows for higher operating frequency and bett...
