Abstract
A new approach to the computation of the transient response of DC-to-DC converters is presented. The key of this approach is the introduction of a new circuit element, ‘the alternor’, defined as a two-port formed by two electronic elements operated as synchronous switches. The constitutive equations of the alternor are used in obtaining the modified nodal equations of the cyclically switching circuit, a frequency-domain description of the power-stage being thus developed. The solution of the equations serves to the computation of the exact, analytic, transient response of the converter. The method is applied to a boost converter operating in the continuous conduction mode
