The circuit functions as a buck-boost inverter without making use of DC-DC converter bridge due to its topology.
Improvements to the impedance networks by introducing coupled magnetics have also been lately proposed for achieving even higher voltage boosting, while using a shorter shoot-through time.
[3] The incommensurate properties of this network open a new horizon to researchers and engineers to explore, expand, and modify the circuit for a wide range of power conversion applications.
[7] Achieving the buck-boost facility in ZSI requires pulse-width modulation.
For shoot through pulses, the carrier wave is compared with two complementary DC reference levels.
