Abstract
A power amplifier that can provide electrical isolation between an input signal and an amplified output signal avoids isolation between the amplifier output and the load to reduce complexity, component count, cost and size over prior power amplifiers. The power amplifier avoids the use of a power transformer to provide electrical isolation, while maintaining electrical isolation between the amplifier and the input signal to satisfy regulatory requirements. A power converter in the amplifier may be directly connected to input power lines, and provide power factor correction and voltage bus regulation to supply appropriate power to the amplifier. The input signal may be electrically isolated from the amplifier through any suitable isolation including optical isolation or magnetic isolation.
