Inhalt:
In this paper, a Second Order Generalized Integrator (SOGI) in combination with a Frequency Locked Loop (FLL) is used for controlling a resonant DCDC Converter. Therefore, the primary current of the transmission path is the input signal of the SOGI. With the filtered outputs v' and qv', the current phase angle can be calculated and the correct switching time is determined by compensation of the signal propagation delay.
