PWM Converter Power Density Barriers
... In order to guarantee a minimum heat sink volume and/or high power density, section 2 presents how the fin geometry of the heat sink can be adapted so that maximum cooling ability for each unit volume is achieved. This cooling ability then is used to compute the power density limit. In sections 3 to ...
