On-State Voltage Measurement of Fast Switching Power Semiconductors
CPSS Transactions on Power Electronics and Applications, 2018 The on-state resistance R ds,on is a key characteristic of unipolar power semiconductors and its value depends on the operating conditions, e.g. junction temperature, conducted current and applied gate voltage. Hence, the exact determination of the R ds,on value cannot rely on datasheet information and requires the measurement of current and on ...
