Abstract
A method for balancing thermal stresses in semiconductor switching devices may include (a) monitoring temperatures of the semiconductor switching devices to provide a temperature difference between two of the switching devices; and (b) based on the temperature difference, providing a zero-sequence component to be used for adjusting conduction times of each of the semiconductor devices.
