WebApr 1, 1997 · Abstract. Passivity-based feedback controllers are derived for the indirect stabilization of the average output voltage in pulse-width-modulation (PWM) controlled DC-to-DC power converters of the ‘boost’, ‘buck-boost’, and ‘buck’ types. The controller design is carried out on the basis of well-known average PWM models of such circuits. WebJan 6, 2024 · There are usually three stages in a DCMG consisting of CPLs as shown in Fig. 5 [ 15 ], including: (1) The source stage comprising various power converters that supply regulated voltage to the DC bus. (2) The interface stage where the LC filter is used to stabilize the CPL and smooth the voltage waveform.
