High Voltage High Frequency Switch

SemiSouth Laboratories, Inc. (SemiSouth), a leading developer and manufacturer of silicon carbide (SiC) power-electronics device technology, proposes the development of a low-cost hybrid switch based on the company’s silicon carbide high-voltage junction field effect transistor (JFET) products. SemiSouth has two principal objectives for Phase I. First, to establish the feasibility of the proposed four-terminal switch by building a 1.5 kV prototype using available 1.6-kV SiC JFETs and COTS electronic components that provide the electrical isolation between the control inputs and the high-voltage outputs; and second to scale the design of the current 1.6-kV SiC JFET to 2-kV in preparation for a possible Phase II effort.
