Power Factor Correction
The power factor correction section consists of the L6561 Power Factor Controller IC (ICPFC),
MOSFET MPFC, inductor LPFC, diode DPFC, capacitor CBUS and additional biasing, sensing
and compensation components (see schematic diagram). This is a boost topology designed to
step-up and regulate the output DC bus voltage while drawing sinusoidal current from the line (low
THD) which is “in phase” with the AC input line voltage (HPF). The design of the power factor
correction section was taken from the L6561 data sheet and information on the operation and
design considerations for the L6561 are contained therein.
Ballast Control
The ballast control section is built around the IR21592 Ballast Control IC, ICBALLAST of the
Demo board. The IR21592 contains an oscillator, a high voltage half-bridge gate driver, an analog
dimming interface and lamp fault protection circuitry. A block diagram of the IR21592 IC is shown
in figure 1 and a state diagram of the IR21592 is shown in figure 2.
