Green power technology inventory

Energy conservation is the theme of power development. How to improve the design efficiency of power supply is the direction that power supply engineers have been working hard. The IIC-China 2011 Spring Show is over. Let's re-invent the new technologies and new products that drive the development of the entire power industry and help engineers improve design efficiency.

Meter solution and related products

Optimistic about the huge market of China's smart grid, ADI presented a three-phase meter solution with performance and price advantages and a relay protection scheme suitable for transmission and distribution.

“ADI has three advantages in the three-phase meter market,” said the person in charge of the booth. “One is the performance advantage. For example, based on the latest ADE7858 three-phase meter solution, the dynamic range is 1,000:1 at 25 degrees. The active energy error is better than 0.1%. The active energy error of 3,000:1 is better than 0.3% at 25 degrees and has long-term stable reliability. The second advantage is the price advantage. The ADE7858 has strong performance. Price competitiveness; the third advantage is brand advantage, ADI currently dominates the market share of the three-phase meter."

In fact, in addition to three-phase electricity meters, ADI has been actively deploying the automatic meter reading market, and has already taken the lead in both PLC and wireless meter reading markets. At present, it is generally believed in the industry that the market for wireless collection will grow rapidly in the next few years. ADI also demonstrated its ADF7020/7021-based solution.

This time, the IIC is not only the ADI, but IDT also exhibited the energy metering chip 90E24 with a dynamic range of 5000:1. It is said to be the first energy metering chip in the industry to achieve such a wide dynamic range. It has the advantage of being able to make single-phase energy meters with a wide measuring range (from 1A to 100A).

The single-phase energy meter based on the current energy metering chip on the market can only achieve the measurement range of 5-20A or 20A-40A. The reason is that the linearity of the ADC inside these energy metering chips is not high enough at both the low range and the high range. Therefore, the dynamic range cannot be made very wide.

Fan Xianzhi, vice president of IDT and general manager of China, said: "Although many leading ADC suppliers in the industry have been leading us in the energy measurement IC market for a long time, only we have made a dynamic range of 5000:1 for the household single-phase meter market. The energy metering IC. Although the 90E24 was launched shortly, it has been approved by many meter manufacturers. The first Design-Win we got was a big German meter manufacturer. At the beginning of this year, Samsung also decided to use the chip to develop wide. Range single phase meter."

The IDT90E2X is a high performance energy metering chip for single-phase, two-wire, single-phase three-wire or anti-tamper meters. It has a 5000:1 industry's widest dynamic range, enabling a single smart meter to simultaneously accurately measure tens of kilowatts of electrical load and renewable resources (such as solar, wind power generated by several watts).

With the increasing number of appliances in the home, more and more users are requesting to install a single-phase meter with a larger range of ranges. The 90E24 chip was developed in response to this market demand trend. Fan Xianzhi said: "Our absolute advantage lies in the highest precision and the widest dynamic range, which allows the integration of a variety of current specifications to simplify production. We next plan to develop a wide-range three-phase metering chip for the industrial market, and then Next, we will develop an electric meter SoC that integrates MCU, RTC, LCD driver, timing sensor and metering chip."

According to reports, IDT90E2X fully meets the requirements of GB/T17215.211, GB/T17215.321 and GB/T17215.323, and can be used for Class 1 or Class 2 single-phase active meters or Class 2 single-phase reactive meters. The chip is available in a green 28-pin SSOP package and is designed to ensure long-term stability in the power grid and external environment.

The 90E24 chip was developed in response to this market demand trend. Fan Xianzhi said: "Our absolute advantage lies in the highest precision and the widest dynamic range, which enables the integration of multiple current meter meters to simplify production.
