The ADE9103/ADE9112/ADE9113are precision simultaneously sampling Σ-Δ analog-to-digital converters (ADCs) for both DC and polyphase shunt-based energy metering applications. The ADE9113 integrates safety certified signal and power galvanic isolation with three simultaneously sampling fully differential 24-bit Σ-Δ ADC channels. The ADE9112 features two fully differential Σ-Δ ADC channels for isolated applications where only a single voltage channel is required. The ADE9103 is a nonisolated, 3-channel Σ-Δ ADC for use in applications where isolation is not required, such as for neutral measurement. The ADE9103/ADE9112/ADE9113 all include a high-gain, current channel best suited for use with a shunt resistor as the current sensor. Multiple ADE9103/ADE9112/ ADE9113 devices can be synchronized to sample simultaneously and provide coherent outputs.

The current channel ADC provides an 86 dBFS signal-to-noise ratio (SNR), at a sample rate of 4 kSPS, over a 1.65 kHz signal bandwidth and a typical gain drift of 13 ppm/°C, which enables down to Class 0.2 accuracy. The voltage ADCs provide an SNR of 91 dBFS over the same sample rate and bandwidth. The high gain on the current channel (IP and IM) aids the use of lower resistance shunts for reduced losses due to heat. The low offset drift of 2 nV/°C offers the performance required for DC metering.

The ADE9103/ADE9112/ADE9113 delivers system cost savings and increased robustness. The main ADE9103/ADE9112/ADE9113 can drive clocks of up to three additional ADE9103/ADE9112/ ADE9113 with a single crystal. The bidirectional, serial port interface (SPI) supports a daisy-chain capability, allowing access to all registers while reducing the required microcontroller pin count. The 28-lead SOIC_W_FP allows more compact layouts. Valid data transfers are ensured with bidirectional, cyclic redundancy check (CRC) and IRQ pin alerts the system of critical faults. The ADE9112 and ADE9113 pass CISPR 32 Class B emissions on a 2-layer printed circuit board (PCB) with the addition of a high voltage capacitor and on a 4-layer PCB with an internal stitching capacitor.

产品详情

The AD-ACEVSECRDSET-SL is a complete Type 2 EVSE 3.6 kW charging cable solution, providing a reference design intended for evaluation and prototyping of electric vehicle (EV) charging systems.

The system includes a 3-channel isolated sigma-delta (Σ-Δ) ADC for voltage and current measurement on the single-phase power input and measurement of the relay voltage for solder contacts detection and relay state of health. Safe operation is enabled by the inclusion of a 6 mA DC / 30 mA rms RCD. Detection of overvoltage, undervoltage, overcurrent, overtemperature and EV diode presence is also available.

A MAX32655 low-power, ARM® Cortex®-M4 Microcontroller implements the logic for system control and communication with the EV over the control pilot interface. A programming and debugging interface are included. The MAX32655 Bluetooth 5.2 interface enables connectivity to external devices.

The design is accompanied by an open-source software stack and reference applications, enabling custom software development to start from a proven implementation validated to meet the applicable standards. An external programmer such as the MAX32625PICO MAXDAP Programming Adapter, or any other similar programmer supporting the SWD interface, is required to enable firmware programming and debug.

The system is designed to comply with the IEC61851 and IEC62752 standards.
