摘要: This paper presents a unified method for developing power stage transfer functions of paralleled DC/DC converters employing automatic load sharing control. The proposed technique uses large signal averaged models to derive the steady-state and small functions, instead modeling used widely in literatures. approach is general can be applied any number modules. For illustration purpose, this two buck with control, corresponding characteristics are analyzed. Moreover, design methodology current share (CS) compensator based on loop gain has been presented. Stability dynamic performance CS control studied. Simulation results three converter converting input DC voltage 12 V, 5 V at 3times20 A presented order verify theoretical reported
