Latest Patents

Zichao Ye's latest patents include a "Switched-bus based resonant switched-capacitor converter architecture." This invention features a cascaded converter architecture that combines a pure switched-capacitor (SC) stage with a resonant SC stage. The design utilizes multiple switching buses to connect the first-stage SC converter with second-stage multi-phase resonant SC converters. By ensuring that the flying capacitors of both stages resonate with the output inductors, charge distribution loss is eliminated. The invention also achieves zero-current switching by adjusting the duty ratio and switching frequency, which reduces the number of switches required and eliminates the need for an intermediate bus capacitor, thereby lowering component count and cost while improving power density.

Another notable patent is the "Cascaded resonant switched-capacitor power converter." This architecture merges a front-end stage with subsequent interleaved SC stages to achieve high conversion ratios. The interleaving control technique addresses practical conversion challenges and allows for the creation of numerous topologies. Examples include a two-stage 4-to-1 conversion using two 2-to-1 ReSC converter stages and an 8-to-1 converter with various configurations.
