基于高频TCM-Q2L控制的中压飞跨电容DC-DC变换器

This article presents a novel control method for a multilevel dc–dc flying capacitor converter for applications in medium voltage range. Quasi-two-level modulation provides the possibility to obtain low flying capacitance even below 1 μF, whereas the triangular current mode controller part enables to achieve zero voltage switching at turn-on for a wide operating range, lowering power losses, and p...
