Motivation:The short-circuit protection methods for power devices can be divided into two main categories: detecting short-circuit current and detecting voltage drop. The current detection method is commonly done through a Sense FET or a shunt resistor, while voltage detection is referred to as desaturation protection. Most power modules do not have an integrated Sense FET, … Read more
If we compare a pure electric vehicle to a running beast, the motor is the heart, and the motor controller is the “nervous center” that precisely regulates the heartbeat. Hidden deep within the vehicle, it directly determines the smoothness of power output, energy efficiency, and driving safety—this article will break down the structural logic of … Read more
