Engineers have been designing switch-mode power converters for some time now. If you’re new to the design field or you don’t compensate converters all the time, compensation requires some research to do correctly. This training series will break the procedure down into a step-by-step process that you can follow to compensate a power converter. We will explain the theory of compensation and why it is necessary, examine various power stages, and show how to determine where to place the poles and zeros of the compensation network to compensate a power converter. We will examine typical error amplifiers as well as transconductance amplifiers to see how each affects the control loop and work through a number of topologies/examples so that power engineers have a quick reference when they need to compensate a power converter.
Why should I take this training?
- Stability is a major concern of any power supply
- Careful consideration must be given to all aspects of power supply design (modulator, error amplifier and output filter)
What will I learn?
- Compensation design objectives and examples
- Theoretical analyis of power stage gain for different topologies and control methods
- Examples of feedback networks with frequency response
- Examples of different compensation strategies
