Reference Design of Sine Wave Inverter


Reference design of a 50Hz/60Hz pure sine wave inverter that can be utilized as a basic inverter at residential or business software.

Are you planning to make a battery energy vitality storage system in your residential use? This reference design is a general-purpose sine wave inverter. This method generates 50Hz/60Hz with 230V AC generated from the battery pack. The identical design will be utilised for constructing a low-frequency and a high-frequency inverter. The reference design employs a low-cost MCU low and high-frequency H-Bridge drive. The protection of the battery within the reference design is managed by an clever battery administration system (BMS).

The pure sine wave reference design has a capability (score) vary from 800VA to 1800VA which is predicated on the battery measurement and backup requirement. The design employs Renesas RAA489206, a 16-cell battery front-end (BFE) IC, which periodically scans battery standing and the working surroundings to optimize battery life and stop catastrophic failures. The design additionally options an LCD show which reveals numerous battery efficiency statistics.

The reference design options an RL78/G14 microcontroller (MCU) operating at a frequency of 32MHz. The MCU presents a number of built-in security options that may detect unlawful operation of {hardware}, furthermore, it may possibly allow assist for the family equipment security normal (IEC/UL 60730).

Benefit of the Reference Design​:

  • A low-frequency and high-frequency inverter will be derived from the identical answer.
  • Remoted system to trace the AC output.
  • Auxiliary flyback energy provide for remoted methods.
  • RL78/G14 low-cost MCU performs the low and high-frequency H-Bridge drive.

Goal Purposes:

  • Residence Inverter
  • Normal Inverter
  • Battery Administration System
