Digital Power Supply Design Workshop

When: 
March 3, 2020 9:00 am in Garching, Germany
Laboratory based digital power supply design workshop providing design engineers an in-depth look at the design of modern, robust switch mode power supplies.

Introduction

This section covers wireless network trends, key technologies, and problem statements for smart grid IoT. 

System-Level Examples for Wireless Networks on Smart Grid IoT

This section covers system-level examples for wireless networks on smart grid IoT. We will provide software- and system-level details for two system examples: 6LoWPAN-Contiki and sub-1GHz sensor to cloud industrial IoT gateway reference design. 

Summary

This section summarizes the wireless network challenges and solutions for a smarter grid IoT training series. 

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.

Introduction to mechanical water meters and EN ISO 4064

This section covers the basics of mechanical water meters and the principle of operation for impeller based water meters. There are multiple standards for water meters around the world; the EN ISO 4064 is relevant to all European countries and has been adopted under a different name in some other regions as well.

Inductive sensing with TI FemtoFET and CC1350 Wireless MCU

Water and heat meters share multiple system building blocks, such as the metrology sub-system and the application sub-systems, the Wireless communications part, the InfraRed optical port or the power solution. In this section, we will cover a new ultra-low cost single-chip LC-sensing solution utilizing the CC1350 Wireless MCU and its Sensor Controller Engine. Two external LC-tanks with a TI FemtoFET device each implement two rotation detection sensors, which measure the rotation of a half-metal/half-nonmetal disc, often used in mechanical water meters.

Bidirectional InfraRed PHY communication with a single IR LED

Some EU standards like EN1434-3 for heat meters require optical interface as per EN62056-21, where two separate IR LEDs are used (one for receive and one for transmit direction). TIDA-01212 shows an alternative approach, which uses a single IR LED to implement a bi-directional IrDA PHY link with 9.6 kbps in half-duplex mode. The design approach can  the system reduce cost of any smart (sub-)metering device by replacing the legacy optical IrDA PHY modules with two separate LEDs.

7-segment LCD control thru SW and GPIOs

This module covers the “Innovative 7-Segment LCD Control Using GPIO Pins and SW” section of the “Single-chip Smart Water meter with Dual-band RF link and InfraRed port” training series.

Overview of temperature measurement in heat meters

This section introduces the heat and cold meter training series. The series covers the basics of RTD sensors and their usage in heat and cold meters, as defined in the EN1434 set of standards.

Measuring RTD sensors with Delta-Sigma ADS1220 family

ADS1220 Delta-Sigma family uses the ratiometric approach for measuring RTD sensors with the built-in current excitation source. Offset and gain calibration are required before the resistance measurement is converted into a temperature reading by the application MCU.

Differential Temperature Measurement sub-system reference design

TIDA-01526 implements a high-precision Differential Temperature Measurement (DTM) subsystem using a 24-bit, low-power, Delta-Sigma ADC. Heat and cold meter DTM subsystems typically use two 2- or 4-wire RTDs such as PT100, PT500 or PT1000 and can achieve measurement accuracy of 20 mK over a water temperature range of 3°C to 180°C. The MSP430FR6047 application MCU converts the resistance value into a temperature reading in TIDA-01526.

Digital temperature sensor replacement of RTD sensors with TMP116

The TMP116 digital precision temperature sensor for the -55 to +125ºC range achieves higher accuracy than the Class AA PT sensor with a 1-point calibration. A small PCB including TI's TPD1E10B06 or TPD1E04U04 protection devices can be sealed into a RTD metal tube and meet the EN 61000-4-2 and -4-4 levels of ESD protection. The 64-bit internal EEPROM inside TMP116 stores user defined calibration data into the digital temperature sensor, simplifying integration with application MCUs, such as MSP430FR6047, FR6989 or CC13xx/26xx wireless MCU families.
