Part Number: UCD3138 I want to enable fast interrupt of dpwm period interrupt. The initialize code is as follow:
Dpwm3Regs.DPWMINT.bit.PRD_INT_SCALE = 0x04;/* generate an interrupt on each 16 switching cycles(used to reset the integrator) */ Dpwm3Regs…
Part Number: UCD3138 Hello,
I have only found Training Labs 1-4 for the UCD3138, though I have read there are more?
Also, are there links that match each training video to the labs? It seems as though they are scattered and I am having trouble finding…
Hello,
60A is reasonable. You may need hardware change. Increase voltage divider after current amplifier so that there is less voltage to AD13. The max voltage to ADC12 is 2.5V.
Part Number: UCD3138 I am using Fusion digital power studio of single phase PFC.

I have read the document of UCD3138 guide. Could you please specify the controller pin values of Irect_fdbk, Vline_sense, Vbus_fdbk ,Vneu_sense ??
My power rating is 2KW so I…
Hello,
There is no component value on the schematic, so it is hard to make adjustment. It is recommended to use a single ground for UCD, but the schematic shows two separate ground. Please refer to SLUA779B for more details.
