ISOLATED PWM POWER AMPLIFIER

摘要

PROBLEM TO BE SOLVED: To provide a PWM power amplifier whose output is isolated from a power supply, which can be downsized together with its power supply section. SOLUTION: The PWM amplifier that is activated by a carrier signal synchronously with a switching signal of an isolation DC-DC converter is connected to the isolation DC-DC converter adopting a synchronization rectifier circuit that can supply its current in two ways.
