“…Also, it is important to note that the capacitor ESR increases significantly at low frequencies, therefore capacitor losses are extremely high at low frequency components (i.e 100Hz, 200Hz and so on) [112]. The total power loss in the DC-link capacitor can be calculated by using RMS value of the capacitor harmonic current (I ch ) as given in (12).…”

“…The highest input displacement factor is reached when the output voltage is maximum and, therefore, the modulation index is equal to 1 [20], [21]. At low-modulation index operation (low load), higher values of reactive power are absorbed by the cycloconverter, whereas the active power absorbed by the cycloconverter increases and the reactive power decreases with a high modulation index [22]. The reactive power, Q, is estimated from the active power and the input displacement factor, The reactive power demand in stands F4, F5 and F6 is controlled by the active control of reactive power [23], [24].…”
