This paper discusses the potential of a transformerless STATic synchronous COMpensator (STATCOM) intended for installation on the 6.6-kV industrial and utility distribution systems. The STATCOM consists of a five-level diode-clamped pulsewidth-modulation converter rated at 1 MVA and a voltage-balancing circuit rated at 6 kVA. Moreover, this paper designs,(More)
This paper addresses a transformerless medium-voltage adjustable-speed motor drive consisting of two five-level diode-clamped PWM converters connected back-to-back. It is followed by designing, constructing, and testing a 200-V downscaled model to verify the validity and effectiveness of the medium-voltage motor drive. This downscaled model has four split(More)
A highly integrated triple band (800MHz/1.7GHz/2.1GHz) WCDMA transceiver IC which operates at low voltage (1.8V) is described. All functionalities are implemented in a single chip using a 0.18mum SiGe BiCMOS process. The direct conversion receiver consists of triple band preamplifiers, I/Q demodulators, channel select filters, and PGAs. The direct transmit(More)
