Abstract |
A single-stage, isolated, low cost, LC resonant
based power supply circuit incorporating
power factor correction and output voltage
hold-up is proposed. Advantages of this
topology include soft switching of power
devices, close output voltage regulation and
control loop simplicity. The recently
introduced Rectifier Compensated
Fundamental Mode Analysis (RCFMA)
method is used to provide an accurate yet
simple analysis of the circuit. The accuracy of
this analysis method is shown in a comparison
with results from a 5V, 20A prototype.
Compliance with input current harmonic
regulations is demonstrated and overall
performance is assessed. |
