The Influence of the Load Type on the Center Frequency Tuning of the Variable-Flux Biaxial Energy Harvester

Table 5

A center frequency comparison for the PSU up and down sweeps using 10, 100, and 1000 filter capacitors for 100 resistive load.

Filter capacitor value	(up sweep)	(down sweep)	Max voltage in up sweep cycle (mv)	Max voltage in down-sweep cycle (mv)
10	8.52	8.37	907	894
100	8.72	8.17	991	969
1000	9.2	7.83	661	712
