Next-generationVariable Speed Drive (VSD) systems utilize SiC MOSFETs to achieve both high efficiency through reduced bridge-leg losses and high power density through an order-of-magnitude increase in switching frequency or reduction of the DC-link c

Triangular-current-mode (TCM) modulation guarantees zero-voltage-switching across the mains cycle in AC-DC power converters, eliminating hard-switching with a minor ${\approx} {30}{\%}$ penalty in conduction losses over the conventional continuous cu

Dynamic on-resistance (dRon), where the on-resistance immediately after turn-on is higher than the DC resistance, increases the conduction losses in power converters with gallium nitride high-electron-mobility transistors (GaN HEMTs). There exist no

Figures-of-Merit (FOMs) are widely-used to compare power semiconductor materials and devices and to motivate research and development of new technology nodes. These material- and device-specific FOMs, however, fail to directly translate into quantifi

For three-phase AC-DC power conversion, the widely-used continuous current mode (CCM) modulation scheme results in relatively high semiconductor losses from hard-switching each device during half of the mains cycle. Triangular current mode (TCM) modu

Phase-modular buck-boost dc/ac inverters extend the voltage conversion range of conventional buck-type inverter topologies, and accordingly offer significant advantages for variable-speed motor drives powered from DC sources with wide-voltage-ranges

Single-phase inverters and rectifiers in 230 V $_{\text{rms}}$ applications, with a dc-side voltage of 400 V, achieve ultrahigh efficiency with a simple two-level topology. These single-phase designs typically utilize a line-frequency unfolder stage,

The origin of ${C}_{{\mathrm {oss}}}$ and the energy dissipation due to output capacitance can be roughly separated into two types: resistive loss and capacitive hysteresis loss. The resistive losses are due to the resistance of gallium nitride (GaN)
