Power converter performance
3.1
LED current vs. line voltage and load voltage
Nominal (18 LEDs) voltage is 54-56 V. Performance is excellent over a very wide range of
load conditions, even with the AC injection.
3.2
Efficiency and power dissipation
As expected, efficiency drops off at low voltage. The rather high RDS(on) of the
HVLED815PF and the input filter series resistances increase I2R loss due to higher required
input current.
