The MOSFETs used as switching elements provide low on-state resistance, low power dissipation, high breakdown voltage, and high saturation current compared to comparable IGBTs. Trying to supply power with a standard converter/regulator topology inevitably leads to component failure, insufficient power delivery, or an oversized system with low efficiency.įor moderate to high DC power delivery, a bridge topology is a better choice, specifically a full-bridge topology with MOSFETs. Many designers that work on lower power systems may be tempted to try and scale a lower power converter topology to a higher power system, but this does not work out in the designer’s favor. Power delivery with stable DC voltage and current is critical for power regulators/converters, motor drivers, and other applications like lighting and pulse generation circuits. Full-bridge MOSFET driver components can be used in high-side switching regulators or motor drive circuits.
