buck-boost in wireless security cameras and video doorbells

Part 1: Introduction

In this video, you will learn how to build an entire power tree, significantly increase the battery operating time, and stabilize the supply voltage rails during sudden load changes such as turning on the camera or WiFi. You will also learn how you can use buck-boost converters to directly and efficiently drive high power white and IR LEDs for evening and night vision.

Part 3: Li-ion battery discharge curves and estimate battery operating time gains with buck-boost

In this section, you will become familiar with lithium ion battery discharge curves and learn in which use cases a buck-boost converter will significantly increase battery operating time.

Detecting case tamper attacks using inductive switches

The first line of defense against tampering by bypassing current, reversing connections, and disconnecting leads is the meter case. Due to this, it is common for utilities to require some form of intrusion detection system to detect when someone opens a case.  In this section, we will cover how to detect someone trying to open the case of a meter.

Detecting magnetic tampering using hall-effect sensors

For anti-tampering, it is common to try to detect the presence of a strong magnet. In this section, we will cover the use of hall sensors for low-power detection of strong magnetic fields in three dimensions.  Details on our magnetic tamper detection reference design, TIDA-00839, will be provided as well as some of the design considerations that were kept in mind when creating this reference design.  

Hardening a meter against magnetic tamper attacks

In this section, we will cover how to harden a meter against these magnetic tamper attacks by using shunts for current sensors. For poly-phase implementations, I will go over how to use isolated delta sigma modulators to add the necessary isolation to use shunt current sensors and create magnetically immune poly-phase energy measurement systems. The TIDA-00601 and TIDA-01094 reference designs, which show how to implement a poly-phase isolated shunt measurement system, will be discussed as well as the associated AMC1304 high-side power supplies used in these designs.

Summary

In this section, a summary of the entire “Anti-tamper Techniques to Thwart Attacks on Smart Meters” training module would be covered.  This summary would cover the “Detecting case tamper attacks using inductive switches “, “Detecting magnetic tampering using hall-effect sensors “,  and “Hardening a meter against magnetic tamper attacks “ sections of the training series. Links will be provided for the reference designs and design tools that were discussed during this training series.

Introduction to Isolation

This section of training videos will discuss what isolation is, the three types of isolators, and how they achieve isolation. This course teaches the fundamentals of isolation, including the basics of the technologies used by many different Texas Instruments isolation products. Then, build on the previous lesson by learning the most common isolation parameters, that are important to system designs and selecting the correct isolator product.
