GaAs rectification-an enabling technology for high frequency operation of power MOS-gated transistors

This paper discusses three applications of GaAs rectification. The first application is a 600 V GaAs rectifier for power factor correction, the second is the low voltage application of GaAs in synchronous rectification and the third application is a medium voltage GaAs rectifier in output rectification. These applications of GaAs rectification demonstrate the potential performance improvement of this technology. Applications that can justify the cost of GaAs generally benefit in terms of switching performance at elevated temperature or ultra-low Rdson as shown by the examples in this paper
