Abstract
Estimating junction temperature in a power semiconductor includes monitoring electrical current direction so as to determine which of a first and a second power semiconductor is in an on-state, and sensing a voltage drop across the one of the power semiconductors. Voltage drop may be correlated with temperature according to a gain dependent upon a level of the electrical current.
