Control Loop

Using DC-DC Converters in Parallel

by

This article discusses methods in using two DC-DC converters in parallel operation for better reliability and redundancy for devices. A technique that sets out power supplies in parallel is interesting and feasible which takes advantage in inventory and stocking, product commonality, additional output current, and N+1 redundancy. But, this technique is possible by recognizing the … Read more

How to Analyze Control Loop Stability with Bode Plots Using Modern Oscilloscopes

by

This article presents important topics to consider in order to make accurate Bode plots for control loops in switched mode power supplies. Traditionally, the method of choice has been to observe the step response and judge from the timing of whether the control loop is stable and fast enough. However, judging the level of stability … Read more
