In the past week, I worked on the following items: 1.) Worked on fine-tuning PWM. Achieved a power efficiency of 95%. 2.) Looked at more information regarding TikiWiki. Tried one solution out but still have another available to try out. 3.) Proof read the draft regarding Power DC-DC converters. Working with Chang-bo on this. 4.) Sent Changbo a write-up regarding PWM and what was done to fine tune it (to be used in experiment section). 5.) Started fine tuning combination PWM + PFM with 2 voltage domains.
