Overview

Description

There are many different solutions on the market for 1-phase power meters to accommodate the customers' varying ranges of design requirements. To ease the design burden and provide flexibility, Renesas has developed an export power meter for the high-end market using an MCU to avoid the limitations of using system-on-chips (SoCs). This design encompasses the full solution including the MCU, a high-speed photocoupler, AC/DC, power device, and memory.

System Benefits​:

  • Compact design based on 72kHz integrated 900V BJT for 18W power supplies, no optocoupler, accurate voltage cross-regulation, compact AC/DC power supplies for smart electricity meters
  • MCU-based design adds flexibility and expanded memory, DLMS supported
  • Easy security/authentication in addition to using NFC connectivity
