高電壓 12 V – 400 V DC 電流感測參考設計
TIDA-00332
概覽
This Verified Design shows a circuit to measure currents with a common mode of up to 400V using an INA138. This is achieved by creating a simple floating power supply and biasing the INA138 directly from the high voltage source. The 400V in this design is an example. With different components even higher common mode voltages can be achieved. This circuit is tested and includes gerber files, test results and a detailed description of functionality.
特點
- Very high common mode voltage range (12V to 400V)
- 36V CMRR
- Small solution size (only 4 additional components)
已開發完全組裝的電路板，僅供測試與性能驗證，且為非賣品。
