Power Factor Correction (PFC) converters are widely used in engineering. A classical PFC control circuit employs two complicated feedback loops and a multiplier, while the One-Cycle-Controlled (OCC) converter has simple circuit. In OCC converters, voltage loop is implemented with PID multiplier not needed. Although linear theory designing circuit, it cannot be predicting non-linear phenomena converter. this paper, model of Boost proposed based on double averaging method. The line frequency instability predicted by studying DC component, first harmonic component second main effect input output capacitance stability studied. correctness verified numerical simulations experimental measurements.
