Part Number: UCD3138PSFBEVM-027 Hi,
I tested IOUT_OC_FAULT_LIMIT function.
When I changed the value of IOUT_OC_FAULT_LIMIT, the function operated in normal.
But When I changed the value of IOUT_OC_FAULT_LIMIT under 5A , the IOUT_OC_FAULT_LIMIT operate and…
Part Number: UCD3138PSFBEVM-027 Hello, When testing the primary 4-channel drive wave of UCD3138PSFBEVM-027, it is found that the 2-channel PWM of the fixed bridge arm QB1/QT1 is stable,
while the 2-channel PWM of the phase-shifted bridge arm QB2/QT2 is…
Part Number: UCD3138PSFBEVM-027 Hello, is the main circuit on the UCD3138PSFBEVM-027 development board using a diode-clamped advanced phase-shifted full bridge?
Some documents say that the loss of the lagging type is smaller, why do you choose the leading…
Part Number: UCD3138PSFBEVM-027 Hello Guys,
Good day.
How can one change the peak current mode control to a single loop voltage mode control of UCD3138PSFBEVM-027 ?
Thanks and regards,
Art
Part Number: UCD3138PSFBEVM-027 Other Parts Discussed in Thread: UCD3138 , Hello Is there a simulation model for the PSFB evaluation board (UCD3138PSFBEVM-027) of UCD3138? (E.g. LTSpice) Best regards.
Hello Neal,
I do not see any problems with interleaved connection. You can customize the phase with respect to each other as long as you use a communication bus to sync them together.
For the Single Phase Shift, I think that is possible but it may depend…
Part Number: Dear Sir;
I've bought the UCD3138PSFBEVM-027, and try to change PCM(Peak Current Mode) to a single voltage loop.
In the EVM027, FE2 is used for PCM, is there any solution to use a fixed Triangular wave instead of Ipri by software modification…
Part Number: UCD3138PSFBEVM-027 Hello.
When I was testing the UCD3138PSFBEVM development board, I encountered an abnormal phenomenon.
The manual says Vin’s overvoltage protection point is 410V,
When I tested vin at 405V, I found that the output…
Part Number: UCD3138PSFBEVM-027 Other Parts Discussed in Thread: TIDM-PSFB-DCDC , UCC27424 Hello.
On the schematic of UCD3138PSFBEVM and TIDM-PSFB-DCDC, the shunt resistor is located in low sided.
Also, its looks like it measure the voltage from output…
Part Number: UCD3138PSFBEVM-027 Tool/software: Code Composer Studio Hello experts ,
In PSFBFirmware-1.1 programme, I find that POUT_SCALER equal 14850.
system_define.h
#define POUT_SCALER (14850)
I can't understand why POUT_SCALER is set.Thanks for…
