Broadband PWM Power amplifier using approximate 2DOF digital controller

Broadband PWM Power amplifier using approximate 2DOF digital controller

Lately, it is required that the bandwidth of PWM power amplifier is extended. For example, it is in application of the testing power supply of a low ferquency immunity examination, or a class-D ampllifier. In this paper, we show that the bandwidth of PWM power amplifier can be extended by using an A...
