Figure 22. NCP1608BOOSTGEVB Evaluation Board Schematic
The bill of materials (BOM), layout, and summary of
boost equations are shown in Appendix 1, Appendix 2, and
Appendix 3 respectively. This pre
−
converter exhibits
excellent THD (Figure 23 and Figure 24), PF (Figure 25),
and efficiency (Figure 26). All measurements are performed
with the following conditions:
−
After the board is operated at full load and minimum line
input voltage for 30 minutes
−
At an ambient temperature of 25
°
C, open frame, and
without forced air flow
−
The input power, PF, and THD are measured using a
PM3000A power meter
−
The output voltage is measured using a HP34401A
multimeter
−
The output current is set using a PLZ1003WH electronic
load
−
The output current is measured using a HP34401A
multimeter
−
The output power is calculated by multiplying the output
voltage and output current
