摘要:
In a module using a high-speed switching element such as an IGBT for a high-speed inverter, a matching condition is established between the switching characteristic of the IGBT and the recovery characteristic of the diode to be connected thereto in an anti-parallel fashion. As a result, the oscillating voltage appearing in the inverter circuit is suppressed to prevent erroneous operation of the inverter system.
摘要:
In order to provide a highly accurate and reliable temperature sensing circuit and method, a resistor (10a) having a positive temperature coefficient is connected between the gate terminal (4) and the insulated gate electrode (8a) of the voltage drive type semiconductor device (1a), and the temperature is sensed based on a voltage representing a voltage drop across the resistor in a circuit portion between the gate terminal (4) and the other terminal (5).
