EVALSTGAP4SDemonstration board for STGAP4S advanced galvanically isolated gate driver | Evaluation Boards | 1 | Active | The EVALSTGAP4S is a galvanically isolated single gate driver for IGBTs and SiC MOSFETs with advanced protection, configuration, and diagnostic features. The architecture of the STGAP4S isolates the channel gate driving from the control and the low voltage interface circuitry through a true galvanic isolation.
The EVALSTGAP4S board allows evaluating all the STGAP4S features while driving a power switch with a voltage rating up to 650 V. The board is provided with two SiC MOSFETs in a H2PAK-7 package connected in half-bridge configuration. The two STGAP4S drivers are connected in an SPI daisy chain and the high voltage side of each is fed by its own flyback power supply, whose controller is integrated in the driver.
Multiple boards can be connected and share the same logic supply voltage in order to evaluate complex topologies, such as full-bridge inverter. The connection of multiple boards allows the implementation of the SPI daisy chain with more than two devices.
In combination with the STEVAL-PCC009V2 and STSW-STGAP4 GUI, the board allows to easily enable, configure, or disable all of the driver's protection and control features through the SPI interface. Advanced diagnostic is also available thanks to the driver's status registers that can be accessed through the SPI. |

EVALSTPM-3PHISOThree-phase full shunt electricity meter evaluation board based on STPMS2, STISO621 and STM32F413RH | Evaluation Boards | 1 | Obsolete | The EVALSTPM-3PHISO evaluation board implements a complete three-phase energy meter with low-cost shunt current sensors.
The solution is based on the STPMS2 device, a double channel, 24-bits second order sigma-delta modulator, measuring voltage and current for each phase through a voltage divider and a shunt current sensor. Sensing circuitry and PCB layout are optimized to maximize signal-to-noise ratio for optimal accuracy.
The STPMS2 oversamples the signal using a 4 MHz clock distributed in a synchronized way by the microcontroller and outputs voltage and current sigma-delta bitstreams, multiplexed on the same pin.
The two-wire communication between STPMS2 modulator and MCU is isolated by STISO621W, 6 kV galvanic isolated interface, allowing up to 100 Mbps rate and low pulse distortion (<3ns) for safe and fast data transfer between isolated domains.
The FW embedded in the solution exploits the DFSDM filters of the STM32F413RH to convert the six bitstreams into 24-bits voltage and current data, at 200 us rate. All the metrology parameters are computed real time on a 200 us basis.
Two LEDs are available for active and reactive pulses generation.
The FW also implements a virtual com port communication to easily access the internal parameters to read metrology data, to modify the internal configuration for a high flexibility of the application, and to calibrate the board. |
