“…The control variables are now the primary phase shift, φ' S , and the secondary phase shift, φ S . For the phase-modulated waveform of V 1 , whose amplitude is V dc and whose dutycycle is linked to φ' S , the following expression occurs: (17) In order to obtain a 24 V amplitude waveform for V 1 , same as the one displayed in Fig. 3, V dc in this primary full-bridge configuration must be the half of V dc in the half-bridge configuration, so that, in the following power equations, obtained by replacing (17) in (10) and (15), and considering a 90° phase delay φ D , V dc is 24 V:…”
