Abstract

Method () for ascertaining a parameter (I_avg, I_N, I_P, V_c), wherein the parameter (I_avg, I_N, I_P, V_c) characterizes a current or a voltage in a circuit arrangement (). The circuit arrangement () comprises an inductor (L) through which an alternating choke current (I_L) flows. The method comprises the steps of: ascertaining () at least one duration (TN) between two zero crossings (N_−, N_+) of the choke current (I_L), or a duration (TNE) between a zero crossing (N_−, N_+) and a vertex (E_−, E_+) of the choke current (I_L); ascertaining () the parameter (I_avg, I_N, I_P, V_c) as a function of the ascertained duration (TN, TNE).
