Power rectifier with integrated current sensor

Abstract

In this paper, high voltage power rectifiers with integrated current sensors are reported for the first time. Devices with a 600 volt blocking capability were designed and fabricated with current ratings of 20 and 80 amperes. 2-D computer modeling of the device structure was performed to achieve the designed breakdown voltage as well as sufficient isolation between the current sensing element and the main device. The integrated current sensor exhibits linearity and temperature independence characteristics which are desirable for current monitoring in the power circuits.
