Abstract
This paper investigates the energy transfer modes of the quasi-Z-source (qZS) DC-DC converter, and accordingly, presents the critical inductor design considerations. The energy transfer modes of the qZS DC-DC converter are generally classified into the continuous conduction mode (CCM) and discontinuous conduction mode (DCM) when considering whether the inductor current reaches zero. In addition, the CCM can be further divided into a complete inductor supply mode (CISM) and an incomplete inductor supply mode (IISM) when comparing the minimum inductor current and the maximum load current. The critical inductance under the CISM, IISM, and DCM for the qZS DC-DC converter is derived in this paper within a specific range of the loading and input voltages in this paper. The capacitor voltage ripple in the impedance network and the output voltage ripple in these energy transfer modes are also obtained. Both simulations and experimental tests are presented to validate the theoretical analysis.
