A switching power converter is designed to have efficiency of 95% when the output load is 100 W. The efficiency increases linearly up to 97% with 200 W output (i. e., efficiency is 96% at 150 W, and so on). Similarly, the efficiency decreases to 94% at 50 W output. The converter will be damaged whenever the power dissipated inside it exceeds 6 W. If the converter is intended to operate for output loads between 20 W and some maximum limit, what is the upper limit of output power that can safely be supplied
