High Voltage Power Classroom

Welcome to this installment of EE Classroom on High Voltage Power.


With the proliferation of HEV/EVs driving more practical 48 V electrical subsystems and the reliance on more stable and efficient power transmission lines grows, so does the need to create advanced high voltage designs. More complicated than traditional wiring in combustion-engine vehicles , high-voltage components require larger and appropriately shielded connectors, larger and heavier cables to handle the high power, and quick-charging systems.


In this classroom, you will learn the basics of high-voltage DC technology including techniques available to boost lower voltages. Tutorials will also guide you through the inner workings of battery management systems, the unique challenges of EV charging systems, and the benefits of high voltage DC transmission, converters, components, and systems.


Charge ahead...

HVDC transmission system architectures and use cases

Working with higher voltages, Part 1: Voltage boosters

Working with higher voltages, Part 2: Voltage multipliers

Over a century of high voltage DC power transmission

HVDC is often used to connect unsynchronized AC power networks.

Learn techniques for a modest amount of lower voltages boosting and increasing voltage to a higher value.

Designs and considerations change dramatically when output voltage goes from 100 V and into >1000 V range.

Improvements in HVDC technology have generally been driven by advancements in power components.
