ADC and sampling option

[SProg]

I want some advice on an programming issue.

Using: STM32F107I am running an 10kHz interrupt from PWM channel.Interrupt lasts about 40usec and being contisiously.I need to measure 4 sensors.3 of them are LTS-6NP which going to measure the current per phase on the VFD and one isolation amplifier which gonna focus the VDC.I guess the best solution is using DMA which will fill my buffers with ADC values.But even DMA need IRQ to inform me that transfer is done.How can i secure,that i will have my adc samples and compute some staff (like Irms) without losing my PWM's IRQ;
