This digest explores the power conversion of triangular pulses into rectangular ones, a technique widely employed for thermally stable linear mode operation. With this research, we extend the application of this same technique to the electro-thermally unstable linear mode operation of power MOSFETs. Experimental evidence, verification and an analytical model are provided to demonstrate the validity and advantages of this approach, which allows for no additional testing and accelerated time to market. In automotive, the ability to address this kind of behavior is necessary in case of capacitive pre-charge or active clamp, where a linearly decreasing current leads to a triangular dissipated power.
