Lesson 1 - The 3 Essential Power Supply Considerations
Discusses the three essential power supply considerations: voltage, current, and regulation.
Lesson 2 - 9 Basic Power Supply Specs
Discusses nine basic power supply specifications: output voltage, output current, output power, load regulation, line regulation, ripple and noise, transient response, duty cycle, and efficiency.
Lesson 3 - Linear vs. Switching Power Supplies
Demonstrates the two main types of power supplies: linear and switching, how they work, their advantages and disadvantages, and when to use each type.
Lesson 4 - Using & Understanding Constant Voltage and Constant Current Modes
Covers the two main modes of operation for a power supply: constant voltage (CV) and constant current (CC). It covers how they work, their advantages and disadvantages, and when to use each mode.
Lesson 5 - Power Supply Readback
Discusses the readback capabilities of a bench power supply.
Lesson 6 - Using Remote Sense Connections to Supply Accurate Power
Explains the use of remote sense connections to supply accurate power to a load.
Lesson 7 - Combine Multiple Outputs for More Power
Learn how to combine multiple outputs from a bench power supply to provide more power. This can be useful for applications that require a high current or voltage, such as powering a large motor or testing a high-power device.
Lesson 8 - Temperature Effects
Discusses how the temperature of a bench power supply can affect its performance. As the temperature of a power supply increases, its output voltage and current can decrease..
Lesson 9 - Transient Response and Load Regulation
Explains how the transient response and load regulation of a bench power supply can affect its performance.
Lesson 10 - Four Tips for Working with Noise Sensitive Devices
Provides four tips for working with noise sensitive devices using a bench power supply.
Lesson 11 - Considerations for Powering Low Power Devices
This lesson covers the importance of understanding the power requirements of the device under test, the different ways to power low power devices, the limitations of bench power supplies when powering low power devices, and the use of external power supplies to power low power devices.
Lesson 12 - Characterize Power Use Over Time
Describes how to characterize the power use of a device over time using a bench power supply.
Lesson 13 - Vary Output Levels Using Output List Mode
Focuses on how to vary the output levels of a bench power supply using output list mode. The lesson covers the purpose of output list mode, the syntax for creating an output list, and the steps for using output list mode.
Lesson 14 - Synchronizing Output Turn-on and Turn-off
Covers the feature on some bench power supplies that allows you to synchronize the turn-on and turn-off of multiple output channels. This can be useful for testing devices that require multiple channels to be powered up at the same time or to ensure that there is no transient voltage when a channel is turned off.
