A Converter-Level on-State Voltage Measurement Method for Power Semiconductor Devices
IEEE Transactions on Power Electronics, 2021 This letter proposes a converter-level method for measuring the on-state voltages of all power semiconductors in a single-phase inverter by using a single circuit only. The proposed circuit distinguishes itself by connecting to the middle-point of each phase-leg, instead of the two power-terminals of individual devices as conventional methods do.

Converter-Level Reliability of Wind Turbine With Low Sample Rate Mission Profile [PDF]
IEEE Transactions on Industry Applications, 2019 The thermal dynamics of power semiconductors and power capacitors are closely related to the reliability and affect the cost of power electronic converter. However, the component loading in a wind turbine system is disturbed by many factors of the power converter, which presents various time constants from microseconds to hours. To determine the system

Converting Level Set Gradients to Shape Gradients [PDF]
, 2010 The level set representation of shapes is useful for shape evolution and is widely used for the minimization of energies with respect to shapes. Many algorithms consider energies depending explicitly on the signed distance function (SDF) associated with a shape, and differentiate these energies with respect to the SDF directly in order to make the ...
