As dual board net systems — vehicles with both a 12 V and 48 V bus — increase in popularity, high power, bidirectional 48 V to 12 V DC/DC converters have become key building blocks in the architecture of today’s automobiles. To optimize overall vehicle efficiency, energy must be transferred in either direction between the 12 V and 48 V batteries, depending on the vehicle’s electrical demands and the state of the batteries’ health.
Therefore, a complete 3 kW, 48 V / 12 V buck-boost converter design is required that utilizes an insulated metal substrate (IMS) with a heatsink for the power stage, with a standard FR4 controller board mounted on top. In general, these types of converter designs cannot operate at maximum efficiency over a wide power range. However, this design features six modular power stages capable of 500 W each.
