Abstract

Construction principles and waveform diagrams of scanning converters (SCs) with pulse-width and pulse-frequency-width modulations (PFWMs) that are used in analog and digital control systems for valve converters are considered. Spectral characteristics of SCs of various classes in a wide frequency range of the harmonic interference signal are comparatively analyzed based on mathematical simulation in the Matlab+Simulink environment. The high interference immunity of integrating SCs with PFWMs is proved.
