ABSTRACT:
A power supply system for powering backlight lamps in a flat panel display with reduced dimensions and increased power efficiency. The power supply system includes a converter circuit for converting an alternating current (AC) signal from an AC power source to a high direct current (DC) signal, and a high voltage (HV) inverter system that includes a power stage circuit, a transformer circuit, and a current balance circuit. The HV inverter system is coupled to the converter circuit and specifically configured to convert the high DC signal into an AC output signal to power the backlight lamps.
