In this paper, the authors propose a novel speed estimator having a hybrid architecture in order to estimate both the rotor speed and the inductance variation simultaneously. The proposed estimator consists of an error between the flux derived from the stator voltage equation and the flux estimated from the rotor flux observer. Introducing the correction term into the estimator increases the estimation ability of the conventional speed estimator even though the motor flux is saturated. The error convergence of the proposed speed estimator is examined by performing the simulation. Furthermore, the experimental results show the validity of the proposed method.","PeriodicalId":347959,"journal":{"name":"APEC 2000.

In this paper, a design and evaluation of the DC-input version of a 900-W server power supply is presented. The AC-input version of this power supply is leveraged from the AC-input version by using the same output stage, and by replacing the AC front-end in the AC-input version with a DC front end which provides the same input voltage to the output stage. By adopting this design approach, it is possible to achieve design modularity, design standardization, minimize the design time, optimize utilization of resources, and minimize the cost. The DC-input version uses a cascade connection of two DC boost converters because of its superior performance compared with other topologies.","PeriodicalId":347959,"journal":{"name":"APEC 2000.

The paper analyzes a nonisolated, two-inductor, step-down power converter and presents its application to power factor correction, when operating in the continuous conduction mode with average current mode control. The input current of the converter is continuous, since one of the inductors is on the line side. Moreover, for a proper coupling of the two inductors, the ripple of the input current can be significantly reduced. Thus, a PFC preregulator with low output voltage and low-ripple input current is obtained. The paper also presents experimental results for a 48 VDC output-voltage and 200 W output-power power factor correction preregulator, operating with 230 VRMS input voltage.","PeriodicalId":347959,"journal":{"name":"APEC 2000.
