Dean Venable pioneered a new method for analyzing and compensating power supply control loops (*all servo loops* for that matter). At Venable Instruments, we have continuously refined our Frequency Response Analyzer systems, providing features such as isolated/floating inputs and outputs, modular instrument architecture for upgrades and software featuring circuit synthesis and simulation. Below we've pulled together top content that address stability analysis:  **Blog Content** [Stability Analysis of Switching Power Supply Feedback Loops (Series of 4 Blog Posts)](https://web.archive.org/web/20260112204438/http://www.venableinstruments.com/blog/stability-analysis-switching-power-loops?__hstc=753710.5ebe6815c8dd0c269712e1ba5abdf577.1768250694223.1768250694223.1768250694223.1&__hssc=753710.1.1768250694224&__hsfp=2342104699) [Feedback Loop Injection Levels for Measuring Loop Gain](https://www.venableinstruments.com/blog/feedback-loop-injection-levels-for-measuring-loop-gain) [Using the Servo to Set Feedback Loop Injection Levels for Measuring Loop Gain](https://www.venableinstruments.com/blog/using-the-servo-to-set-feedback-loop-injection-levels-for-measuring-loop-gain) [How Much Phase Margin do I Need?](https://www.venableinstruments.com/blog/phase-margin-need) [Current Mode Control Power Supplies](https://www.venableinstruments.com/blog/current-mode-control-power-supplies) [Modern SMPS Control Loop Testing](https://www.venableinstruments.com/blog/modern-smps-control-loop-testing) **White Papers** [Stability Testing of Multi-Loop Converters](https://www.venableinstruments.com/stability-testing-of-multi-loop-converters-wp) [New Techniques for Loop Stability Testing in Power Factor Correction Circuit](https://www.venableinstruments.com/loop-stability-testing-wp) [Optimum Feedback Amplifier Design for Control Systems](https://www.venableinstruments.com/optimum-feedback-amplifier-design-wp) [Specify Gain and Phase Margins on All Your Loops](https://www.venableinstruments.com/specify-gain-and-phase-margins-on-all-your-loops-wp)   Other Best of Content Pages [Best of Content Impedance Measurements in the Data Center](https://www.venableinstruments.com/impedance-measurements) [Best of Content Source Load Impedance](https://www.venableinstruments.com/source-load) [Best of Content Transfer Function Measurement](https://www.venableinstruments.com/transfer-function)               Interested in learning more, check out [Venable's Technical Library](https://www.venableinstruments.com/technical-library) #### About Venable Venable provides scalable energy storage and power systems test solutions for precise voltage, current, and frequency measurements, partnering with engineers to ensure battery and power systems around the world will meet stringent field performance demands.  #### Recent news [![Venable Training - Stabilizing Power Supply Control Loops](https://www.venableinstruments.com/hubfs/Venable%20Training%20Front%20Image.jpg) **Venable Training - Stabilizing Power Supply Control Loops** 20 August 2025 ](https://www.venableinstruments.com/blog/stabilizing-power-supply-control-loops) [![The Ins and Outs of System Level Input/Output Impedance Measurements](https://www.venableinstruments.com/hubfs/Imput%20Impedance%20Test%20Set%20UP.jpg) **The Ins and Outs of System Level Input/Output Impedance Measurements** 23 June 2025 ](https://www.venableinstruments.com/blog/impedance-measurements) #### Subscribe Subscribe to our blog to receive emails and updates on scalable power and energy systems test solutions from Venable Instruments.  #### Contact us Venable Instruments 8656 SH 71 West Cuesta Centre, Building E Austin, TX 78735 Office: 512-949-3100 Fax: 512-949-3151
