Analytical Calculation of the Residual ZVS Losses of TCM-Operated Single-Phase PFC Rectifiers
IEEE Open Journal of Power Electronics, 2021 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 ...

Electronic Workshops in Computing, 2012 Crowd-powered systems combine computation with human intelligence, drawn from large groups of people connecting and coordinating online. These hybrid systems enable applications and experiences that neither crowds nor computation could support alone. Unfortunately, crowd work is error-prone and slow, making it difficult to incorporate crowds as first-
