Abstract :
Two actual case studies in which a Venable Systems 350 frequency response analyzer was used and that demonstrate a practical approach to stabilizing and enhancing a power supply´s performance are described. The approach consists of the following: measuring the frequency response of a system; selecting a desired frequency response; designing and implementing an error amplifier and for other compensating amplifiers that fulfill the specifications; and verifying the results by measurement. The system and conventions and two power supplies with specific deficiencies are described. The first case study involves a power supply without a dominant pole output capacitor. The second case study involves a power supply driving a highly damped resonant load. The authors discuss measurement pitfalls.<>
