Shown here is an apples-to-apples comparison between a diode bridge and an LT4320 bridge, both sized to maintain the same temperature rise of 22°C above ambient with a 10A load current as seen in the thermographs. To achieve this, the diode bridge needs a heat sink measuring 6.5 inches x 4 inches and weighing more than 2 lbs. The LT4320 sends the rectifier on a diet, drastically shrinking its size and weight.
