SYSTEM AND METHOD FOR PROVIDING BI-DIRECTIONAL POWER FLOW AND POWER CONDITIONING

摘要

A system and method for providing symmetric, efficient bi-directional power flow and power conditioning for high-voltage applications. Embodiments include a system that comprises a first normally-on junction field-effect transistor (JFET) having a drain that forms a first coupling node and a first normally-off semiconductor transistor having a drain coupled to a source of the first normally-on JFET and a source coupled to a gate of the first normally-on JFET, wherein a high voltage on the first coupling node provides a negative voltage on the gate of the first normally-on JFET resulting in blocking of the high voltage and mitigating power flow through the normally-on JFET and normally-off semiconductor transistor.
