Say you were building a full-wave rectifier. How many simple ways (if any) are there to reduce the THD on the source caused by using a full-bridge rectifier load? Also, If you used a low pass filter and then an isolation TX (or the other way around?), how much would that help to this end (if at all)? I'm sure you would get odd harmonics and that the TX would act as a LP filter in it's own right, but what else do you need to consider, and how can you combat the non-linearity of this load? Thanks!
