STEVAL-ILB001V2 36 W - 220 Vac low-cost HF ballast demonstration board using the bipolar solution for PFC Data brief Features Power supply: 220 Vac Power output: 36 W Boost topology Discontinuous-conduction mode RoHS compliant Description The STEVAL-ILB001V2 demonstration board is a complete reference system for a simple cost- effective PFC (power factor corrector) using bipolar transistors and is intended for low-to- medium power HF ballasts. The proposed bipolar PFC solution targets the low-cost HF ballast market up to 80 W as it provides a simple cost-effective solution without sacrificing THD and PF levels. No additional ICs are required for the PWM signal as the device uses just a power bipolar transistor and a closed- loop feedback which performs the duty cycle modulation and output power regulation. The active PFC solution with bipolar transistor adopts the boost topology operating in discontinuous-conduction mode.
