BACKGROUND. The paper discusses a single-phase bridge self-excited inverter operating into active inductive load. The load voltage is generated by switching the key circuit elements; the current shape is determined by the load parameters and characterized by the higher harmonic spectrum. In practice, the calculations are often focused on the effective inverter load current of a non-sinusoidal shape; its determination is associated with known computational difficulties.
AIM. To develop a method to calculate the effective value load current of a self-excited inverter that does not require decomposition of the current curve into a harmonic series and its subsequent summation.
METHODS. The effective inverter load current was calculated using the theory of residues.
RESULTS. The load current of a self-excited inverter calculated based on expressions obtained using the theory of residues allows to reduce the amount of computation and ensures high accuracy, which is confirmed by experimental studies.
