In these converters, a pulse width modulation (PWM) technique is widely used. On the other hand, to improve power factor in utility AC side of converter a variety of power factor correction (PFC) converters are effectively introduced. For these converters, hysteresis current control method is developed and applying. Usually, this control scheme uses reference sinusoidal wave and upper limit signal which is determined by added constant value to reference signal, as well as lower limit signal which is determined by subtracted constant value from the reference signal. Using these signals, hysteresis current control method for PFC converter regulates its input current within the range that is determined by the upper and lower limit. In this paper the authors propose a simple configuration hysteresis controlled PFC converter which can effectively reduce current ratings of switching power device. The proposed PFC converter controls input line current keeps within the constant upper limit, specified by the switching power semiconductor device rating, as well as lower limit determined by reference sinusoidal wave. From FFT analytical results, the proposed circuit can lower the current rating of switching power device than fundamental component of input line current.","PeriodicalId":320424,"journal":{"name":"Proceedings of the Power Conversion Conference-Osaka 2002 (Cat.

The 1/sup st/ optimized solution produces the lowest value of motor harmonic losses if the skin effect in the rotor bar is not significant while the 2/sup nd/ one gives the lowest value of these losses for the strong skin effect. It is shown that the harmonic losses of the optimized and the commonly used carrier based three-phase and two-phase overmodulation strategies ensure acceptable values of harmonic losses even if the skin effect is taken into account but only up to 96% of the maximal possible voltage region. In this case for the presently used switching frequencies the motor harmonic losses rarely exceed the maximal losses of the normal voltage region. The near constant voltage gain can be ensured for the overmodulation region too. The torque ripples of different overmodulation strategies have about the same values.","PeriodicalId":320424,"journal":{"name":"Proceedings of the Power Conversion Conference-Osaka 2002 (Cat.

The purposes of the proposed control strategy are to correct voltage imbalance of the DC link capacitors, to keep the input power factor at near unity, and to achieve adjustable-speed drive. The five-level rectifier is controlled by the instantaneous-value-compared current control method using multi-band hysteresis comparators. On the other hand, the five-level inverter is controlled by the space vector pulse-width modulation method. The validity of the control strategy is verified by experiments using a 3.7 kW induction motor.","PeriodicalId":320424,"journal":{"name":"Proceedings of the Power Conversion Conference-Osaka 2002 (Cat.

In order to implement the equivalent inertia of the entire elevator system, the conventional simulators have generally utilized mechanical inertia (flywheel) with large radius, which makes the entire system large and heavy. In addition, the mechanical inertia should be replaced each time in order to test another elevator system. In this paper, the dynamic load simulation methods using electrical inertia are presented so that the volume and weight of the simulator system are greatly reduced and the adjustment of inertia value can be achieved easily by software.
