STEVAL-ISV020V1: MPPT for 3 phase brushless dc turbines

Dear ST Community,I would like to use this device for energy harvesting from a 3 phase brushless dc turbines. The MPPT algorithm from this device is created for TEG and solar power, so I wonder it's possible to use this with brushless dc motor.Thank ...

Choosing a Transil for Triac Over voltage protection.

Hi team,I'm working on a 3 Phase (400Vrms) Power board control system. Regarding the over-voltage protection of the triac, AN1996 suggests to use Transil across Gate and A2 of the Triac. 1) When Choosing a Transil, the peak voltage of our system is 5...

When I connected steval-isv021v1 to the PC, the device did not recognize it，how to solve it？

STPOL01A - when will samples be available? when will it be released to the market for buy?

Mastergan1 behavior in unpowered state while current flows over the "diode"

Hello,I am using three Mastergan1 in a 3phase Rectifier. When the Grid is switched on the circuitcharges the DC link Capacitors uncontrolled.I am planning to build a “switch on�? circuit.How much current can the Mastergan1 handle in an unpowered stat...

Connection of Vcc and Pvcc of STDRIVEG600

Hi there,​I am using the STDRIVEG600 to drive FETs for my application. However, I came across some confusion.​Would you please clarify the following question:​Are the VCC (pin 4) and PVCC (pin 5) internally connected as the attached picture with blue...

Need help interfacing with L9305

As I could not find any interface/programming guides in the software documentation section i need help interfacing the L9305 IC via SPI. Also I have a few queries.1) In the SPI section, the MSB is R/W bit. But what does 1 mean Read or Write ? 2) What...

Hello. I am designing a 3 phase inverter with L9907 Motor driver IC. Is there any possible way to use it for an 84V system?

SPV1050 and solar panel current

Hello,I have a circuit with an SPV1050, the max Ibatt is 70mA, I'd like to know what happen if the solar panel can source more than 70mA, i.e 100mA. Is it a problem for the panel or for the chip (i.e temperature increase too much) ?Best regards,Ricc...
