The motor was supplied from a high frequency (20 kHz) AC resonant link via an MCT-based bidirectional converter. Hardware and software implementations of the various motor control functions are presented. The closed-loop observer combines the current and voltage models via a speed-dependent gain. The current model was formulated to operate in the rotor reference frame, and requires only an encoder angle, and not the actual rotor speed for implementation. The closed-loop observer permits the use of a pure analog integrator to calculate an adequate stator flux. The use of an AC resonant link further complicated an all digital calculation of the stator flux. The observer and adaptive controller were tested on a 400 Hz, 2 hp induction motor for low and high speeds. The closed-loop observer showed sensitivity at low speeds. This was attributed to the current model rotor flux estimation. At high speed the closed-loop observer followed the voltage model rotor flux estimation attributes. The MRAS was able to improve the complete speed response by correcting the current model rotor flux observer for errors in the estimation of its parameters.","PeriodicalId":177291,"journal":{"name":"IAS '96.

Krishnan","doi":"10.1109/IAS.1996.557038","DOIUrl":"https://doi.org/10.1109/IAS.1996.557038","url":null,"abstract":"Considerable attention is given to finding compact and low cost converter topologies for permanent magnet brushless motor drives to meet the emerging high volume low performance applications such as in HVAC, air handlers, fans, pumps, small process drives, hand tools, appliance drives and many others in the range of fractional to one hp rating. This paper is concerned with such an attempt to formulate a novel converter topology for a four-quadrant PM brushless DC motor drive. The proposed topology has a single switch per phase limiting the motor drive to half-wave operation. But it also endows unique features with high reliability such as shoot-through free topology by having a switch always in series with a phase winding, operational possibilities even with one or two phase windings failure, reducing the converter losses to half that of the full-wave inverter, reduction of gate drivers and amplifiers, and reduction in logic power supplies requirement. Many of these features result in low cost and compact packaging of the converter for the PM brushless DC motor drive. The machine design modification requirement due to the half-wave operation of the proposed converter is derived in this paper to help in the realization of the proposed motor drive in industrial applications. The formulation and description of the circuit topology and its operation with the motor, their dynamic modeling, simulation and analysis and its comparison to the full-wave inverter fed PMBDC are the key contributions of this paper.","PeriodicalId":177291,"journal":{"name":"IAS '96.

Every DC system is subject to faults, in fact, short-circuits and ground faults can be expected at any point. Even if the maximum and minimum values are generally defined with reference to bolted-fault conditions, bolted faults are rare and the fault usually involves arcing and burning (impedance). Therefore, the limiting value of minimum short-circuit depends on the arcing fault. Since an uninterrupted DC arcing fault can cause significant power system equipment and building damage from the fire and smoke that can be produced (i.e., burning cable insulation), it is necessary to: identify critical fault points; estimate the modes and effects of these faults; examine ways in which they can be located; select the best protection methods to isolate the fault; mitigate system damage and outage time; and maintain personal safety. In addition, surveillance and system configuration management programs should be established to prevent the potential for arcing faults to occur. Finally, this paper discusses the extent of damage that can result from a DC arcing fault and recommends system and protection enhancements to significantly limit this damage.","PeriodicalId":177291,"journal":{"name":"IAS '96.
