| Abstract: | The circuit structure and working principle of CS5484 are analyzed, and the energy power parameter measurement device based on CS5484 is designed and developed. Especially the circuit of the voltage and current channels are emphatically analyzed. This device uses microprocessor STM32F107 which integrated ethernet controller as the control chip, and it can meet the needs of complex control outputs and networking measurements. Using the standard AC signal source to test this device, the results indicate that the voltage measurement error is below 0.2 %, reactive power measurement error is below 0.4 % therefore this device can satisfy the requirements for the power parameter measurement. |
