A UPS, which is mostly employed to protect sensitive loads from disturbances, has such limitations that it dissipates no less energy in running operation because currents flow through two converters in series, it is poor in feeding electric motors which occupy the main loads in industrial plants and that its costs are high to be commonly applied. UPS can be regarded not as omnipotent against voltage dips and short interruptions. We have developed a novel power apparatus termed QBS (quick backup system) to supplement the above drawbacks in UPS, employing one reversible AC/DC converter and one high-speed switch. Normally QBS supplies power directly from a commercial network to critical loads while the reversible converter interconnects with it to charge the battery. When the critical bus voltage deviates from the tolerance range QBS disconnects the high-speed switch and continues to feed the critical loads in UPS mode. The whole power transition is completed within 2 ms. QBS of several thousands kVA has already been put to commercial use in telecommunication centers, electronics manufacturers and others.","PeriodicalId":320424,"journal":{"name":"Proceedings of the Power Conversion Conference-Osaka 2002 (Cat.

The proposed control system is based on an injected voltage vector that is synchronized with a PWM carrier of an inverter. The pole position is estimated from the relation between the injected voltage vector and the saliency of the rotor. The first current difference vector is detected when the injected voltage vector in the estimated pole position direction is added to the motor control voltage vector. Next, the second current difference vector is detected when the injected voltage vector in the opposite direction of the estimated pole position is added to the same motor control voltage vector. Then, the pole position of the rotor with anti-saliency can be estimated from the first and second current difference vectors. This control needs neither motor parameters nor band pass filters. The anti-salient pole type IPMSM can be operated over a wide speed range including zero speed, with a quick response. Good driving of electric vehicles is realized using the proposed system.","PeriodicalId":320424,"journal":{"name":"Proceedings of the Power Conversion Conference-Osaka 2002 (Cat.

To solve the practical problem of sensorless propulsion, DTC method is selected to control sensorlessly the thrust force and stator flux linkage of LSM, combining a voltage prediction control to decrease the variation of flux. To verify the controlled-PM Maglev propulsion theory, the vehicle is propelled by sensorless DTC method at standstill-levitation status with minimum energy-loss method. Experimental results show that, even under an extremely unbalance condition that coercive fore of one the four PM's installed on board is reduced strongly by 25%, the 256 kg-heavy-vehicle could be levitated very well with minimum energy-loss method. At levitation status, the vehicle also has been propelled sensorlessly following the demand position and speed above a low speed of 0.2 m/sec, even in acceleration and deceleration as well as constant speed phases, though there is a strong detent fore due to the large semi-closed slots which give a strong influence to the propulsion operating of DTC.","PeriodicalId":320424,"journal":{"name":"Proceedings of the Power Conversion Conference-Osaka 2002 (Cat.
