Automatic voltage regulator using an AC voltage-voltage converter

IEEE Transactions on Industry Applications, 2000
Voltage sags and extended undervoltages are one of the main concerns of industry today. These voltage sags could cause high negative impact on productivity, which is certainly an undesirable aspect in industrial and commercial applications. Current tap-changing transformers used in distribution systems have proven to be inadequate in solving these ...

Low-voltage CMOS voltage squarer

2009 16th IEEE International Conference on Electronics, Circuits and Systems - (ICECS 2009), 2009
A voltage squarer based on bulk-driven PMOS transistors is proposed in this paper. Circuit topology employs a voltage attenuator and the quadratic I D /V G characteristic of a MOS in saturation. The squarer was designed with a 0.8V supply voltage using standard 0.35um CMOS process, which offers large value of threshold voltage.

High voltage capacitive voltage conversion

2018 IEEE 30th International Symposium on Power Semiconductor Devices and ICs (ISPSD), 2018
A novel high-voltage, ultra-high efficiency monolithic DC-DC Converter is presented. The disclosed architecture was integrated in the X-Fab XT018 SOI process using lateral Super Junction NMOS devices for up to 400V operation. Buck or boost voltage conversion is realized using high-voltage switched-capacitor and gate-driver techniques enabling ...
