PROBLEM TO BE SOLVED: To provide a switching controller capable of reducing temperature difference between upper and lower switching elements to minimum.SOLUTION: When upper and lower temperature detection means constituting a drive circuit detects the temperature of upper and lower switching elements, or when the upper and lower temperature estimation means estimates the temperature of the upper and lower switching elements. A signal generation circuit gives an offset value to a command voltage of a PWM signal to be output to the upper and lower switching element so that the upper temperature and the lower temperature get closer to each other to generate a PWM signal, and outputs the same to the respective switching elements. |
