According to the definition the effective value of voltage V is equal to Vrms as to the mean value of u(t) during the energy transfer time T or kT, where k may be 1, 2, 3, 4 etc. However, in power electronics circuits (e.g. rectifiers, choppers, converters, inverters) the energy transfer time, Δt, in many situations is less than the functions period, T (Δt < T). In such a situation the author asks a question – how can we calculate the effective value of voltage V?
