10 presents the switches arrangement in which tapped-winding realizes all possible cases. As seen, in this switches arrangement, the number of switches is equal to the number of taps and in order to obtain the achievable voltages, in any case one of the switches must be on and others off. 3 presents the position of switches for obtaining the realizable voltages. Now configuration of Fig. 2b is considered. 11 suggests four switches arrangements for this configuration. Every suggested arrangements, in Fig.
In DCM waveform, there is a periodic variation of the voltage amplitude and this causes flicker in incandescent lamps. Of course, flicker depends upon several factors such as human factors, voltage variations, and lamp power and its permissible range has not been fully defined. 31 shows the test results of 1,104 observations by 95 persons. These results are obtained by applying the variations of a pulse amplitude voltage for different amplitudes and frequencies on 1,157 incandescent lamps with powers 25, 40 and 60 W.
3. In this model, all voltage supply is sinusoidal and the phase and amplitude of each supply is proportional with the relevant number of turns of the winding. 1. As seen, VN1 is present as bias voltage in the achievable voltages. It is noted that voltages such as VN1 ?
