Getting Started with Current Sense Amplifiers

The Getting Started with Current Sense Amplifiers series helps engineers learn how to maximize the performance achieved when measuring current with a current sense amplifier (also called a current shunt monitor).

This is a series of short videos, each addressing a different topic.  While intended as a series to be viewed in order, each session is stand-alone and can be viewed without the need to watch it all if there is a specific topic you are interested in learning more about.

Introduction to Power Electronics

Power electronics impacts our lives in so many ways - from new power circuits that extend battery life to voltage regulators that help manage and distribute energy more efficiently from the grid to the consumer. This four-part Power 101 fundamentals course covers several topics that a design engineer needs to understand when it comes to power management design.

Solar Inverter Systems Made Simple Training

Systems Made Simple: Solar Inverters

One of the key systems in a solar energy harvester is a solar inverter. A solar inverter, or any kind of inverter for that matter, will take a Direct Current voltage input and convert it to an Alternating Current output that can be used to power standard appliances and electronics in a home or business. While just about any high power DC source can be used, the largest sector of inverter growth is in renewables, particularly solar applications. Watch this series to help you mitigate multiple solar inverter design challenges.

Get to know your gate driver

Know Your Gate Driver

We live in a world where design engineers are on a seemingly constant pursuit for higher efficiency. Everyone wants to do more with less power. Higher system efficiency is a team effort that includes (but is not limited to) better-performing gate drivers, controllers and new wide-bandgap technologies. In this multi-part video series, we will focus on the gate drivers and how choosing the right driver can help your whole system design. You will learn about important gate driver specs, why they’re important, and how they can influence the systems around them.

How to design multi-kW DC/DC Converters  for electric vehicles

How to design multi-kW DC/DC converters for electric vehicles (EVs)

We are all well aware that the demand for Electric Vehicles (EV) is increasing rapidly. This eight-part training session begins with a description of a typical EV system in part 1. Part 2 is a brief description of how both Lead Acid and Lithium Ion batteries are charged. Part 3 focuses on the types of power factor and harmonic currents. Part 4 discusses power factor correction and the typical boost PFC stage. Part 5 concentrates on the Phase Shifted Full Bridge topology, including the reasons why it is used and a detailed description of how it operates.
