Abstract
A solid-state power converter using a transistor bridge structure and symmetry modulation to improve output stability when driving resonant loads. The power converter utilize a direct coupled driver for each upper switching transistor, permitting a wider control range than a transformer. In addition, various circuits to protect the load and the converter include: power limiting, surge reduction, thermal limiting, input over-voltage protection, output over-voltage shutdown, ground-fault shutdown, re-start delay, soft-start, and low-current off-on switch.
