Considerations for Measuring Loop Gain in Power Supplies
Power Supply Design Seminar Considerations for Measuring Loop Gain in Power Supplies Reproduced from 2018 Texas Instruments Power Supply Design Seminar SEM2300, Topic 6. TI Literature Number: SLUP386. 2018 Texas Instruments Incorporated Power Supply Design Seminar resources are available at: Considerations for Measuring Loop Gain in Power Supplies Manjing Xie Abstract Loop gain measurements show how stable a Power supply is and provide insight to improve output transient response. This presentation discusses the theory of open -loop transfer functions and empirical loop gain measurement methods. The presentation then demonstrates how to configure the frequency analyzer and prepare the Power supply under test for accurate loop gain measurements.
Figure 6 – Measuring loop gain of a power supply in open-loop setup. When the feedback loop is broken at any point, such as that shown in Figure 6, looking backward, i.e. looking into point B, and applying Thevenin’s theory, the circuit is equivalent to a voltage-controlled voltage source (VCVS) in series with an output impedance, Z
