About the feedforward control calculation problem in 5.2 (FF_VqdffComputation)
The feedforward control block diagram in the official data is as follows: However, the calculation result in FF_VqdffComputation is different, taking ΔUq as an example.ΔUq = (Ke + Ld*Id)*2*pi*p*fr + UqThe code in FF_VqdffComputation is as follows:/*q...
Resolved! Cost-efficient remote reset of STPM3x
STPM32 is used for an e-meter application. Idea is to use 2-pin UART connection, isolate only the RX and TX with optocouplers and not to use the SYN and SCS for reset.According to datasheet on page 68 the remote reset can be performed in two ways:· ...
L7985A with lower quiescent current.
I'm searching for a pin to pin replacement for the L7985A with same pinout, same (or better) characteristics, with a lower quiescent current. Any help will be very appreciated. Thanks.
Regarding shunt resistor value in STPM10 mettering device.
Hello. I try tu adjust the value of shunt resistor in STPM10 electronic circuit.First I placed one 0.5mOhm resistor value, and I watched that 40W lamps meassurement is not very exact. Maybe I should to increase this value. But I have read that maxim...
Resolved! Stop LED flickering with a Snubberless™ Triac
I have a problem with triac BTA06-600B, when I try to power off some LED lamps they start flickering. I use triac to manage the main power (220V 50Hz), if the load is a traditional, halogen or cfl lamp all works fine. I tried to unmount the snubber c...
push pull converter design
I made a push-pull converter using sg3525a. my problem is the output voltage will drop when I connecting 100-watt load or more.input voltage is 24 volt and the output is 350 volt. the frequency is 100khz. using MOSFET irfp4568. using RC snubber with ...
