The realisation of the control of an AC/DC converter using a motor control DSP

A digital signal processor (DSP) controlled, isolated, power factor corrected, two-stage AC/DC converter is presented. All the control functionality is implemented using the 28 pin, analog devices DSP, ADMCF328, which is referenced to the secondary. The primary control voltages are magnetically sensed. The DC/DC stage control voltages are sensed using the AD7811 ADC. The internal serial port of this device is used to serially transmit its output data to the DSP
