Abstract :
PWM DC-DC converters under one-cycle control, charge control, or quasi-charge control is analyzed by using a unified sampled-data model. Large-signal analysis, steady-state analysis and small-signal analysis are addressed analytically. The orbital nature of the nominal periodic solution is preserved. Various transfer functions are derived. Compared with the averaging approach, the sampled-data approach is more accurate and systematic
