Abstract :
This paper introduces the design and implementation of a full FPGA oriented PWM/CPM controller. The controller realization has been enabled by newly developed ADC and high-resolution DPWM peripheral units based on delay line technology that has been specially modified to FPGA design and constrains. The new ADC is capable of converting a sample with resolution of 10 bits within 300ns. The DPWM has demonstrated capability of producing 11bit signal at 1.6MHz. CPM operation is verified on a 12-48V, 100W boost converter.
