TIDA-00912 Shunt-Based High Current Measurement (200-A) Reference Design with Reinforced Isolation Amplifier | TI.com

TIDA-00912: The TIDA-00912 TI Design provides a complete reference solution for isolated current measurement using external shunts, reinforced isolation amplifiers, and isolated power supply. The shunt voltage is limited to 25 mV max. This reduces power dissipation in the shunt to enable a high current measurement range up to 200 A. Shunt voltage is amplified by a instrumentation amplifier configuration with a gain of 10 to match the input range of isolation amplifier for better signal to noise ratio. The output of isolation amplifier is level shifted and scaled to fit the complete input range of 3.3-V ADCs. This design uses free running transformer driver operating at 410 kHz for generating isolated supply voltage in a small form factor to power high voltage side of the circuit.

TIDA-00834 High Accuracy Analog Front End Using 16-Bit SAR ADC with ±10V Measurement Range Reference Design | TI.com

TIDA-00834: The TIDA-00834 reference design accurately measures voltage and current inputs using simultaneously sampled, 16-bit, ±10 V, bipolar input SAR ADC critical to identify power systems malfunction and power quality related failures accurately and quickly. This results in reduced power systems downtime. The AFE includes signal conditioning based on precision instrumentation or precision amplifier for current measurement upto 125A and opamp based signal conditioning circuit for voltage measurement upto 300V. The gain amplifier for voltage and current inputs are used to scale the sensor output to the ADC range. Coherent sampling of the analog input signals is implemented using comparator and FPGA. The power supply for data acquisition front end is generated using a +5V input.

TIDA-00835 High Accuracy ±0.5% Current and Isolated Voltage Measurement Ref Design Using 24-Bit Delta-Sigma ADC | TI.com

TIDA-00835: The TIDA-00835 reference design allows for accurate voltage and current measurement using a bipolar input configuration by incorporating a four- channel, 24-bit simultaneously-sampling differential input Delta-Sigma ADC over wide dynamic range. The ADC is configured to measure ±2.5 V bipolar input. The inputs are scaled to ADC measurement range of ±2.5V using a fixed gain amplifier. This AFE chains two ADCs together using a common external clock to expand the number of input channels to eight while simultaneously sampling all of the input channels. By having more measurement channels per module, overall system cost is reduced.

TIDA-00366 Reference Design for Reinforced Isolation 3-Phase Inverter with Current, Voltage and Temp Protection | TI.com

TIDA-00366: The TIDA-00366 reference design provides a reference solution for 3-Phase inverter rated up to 10kW designed using reinforced isolated dual IGBT gate driver UCC21520, reinforced isolated amplifier AMC1301, and MCU (TMS320F28027). Lower system cost is achieved by using AMC1301 for motor current measurement interfaced with internal ADC of MCU and use of bootstrap power supply for IGBT gate drivers. The inverter is designed to have protection against overload, short circuit, ground fault, under/over DC bus voltage and IGBT module over-temperature.

TIDA-00445 Shunt-Based 200A Peak Current Measurement Reference Design Using Isolation Amplifier | TI.com

TIDA-00445: The TIDA-00445 TI design provides a reference solution for isolated current measurement using shunt and isolated amplifier. By limiting the shunt voltage to 25mV, this design is able to reduce power dissipation in the shunt and achieves a high current measurement range of up to 200A. Shunt voltage is further amplified by precision Opamps in instrumentation amplifier based configuration with a gain of 10 to match the input range of isolation amplifier. The output of isolation amplifier is level shifted and scaled to utilize the complete input range of 3.3v ADC. This design uses free running transformer driver for generating isolated supply voltage for the high voltage side of the circuit. Small form factor for the power supply is achieved by the operation of driver at 400 KHz.
