A multiple-CCFL (cold-cathode fluorescent lamp) inverter that had a complete safety protection was developed. When it happened any failure detected the inverter shut off all the high-voltage outputs. The protection circuit controlled all the STOP signals of each controller IC using a multiple-input NAND gate buffer.
