The STEVAL-ILB001V2 is a 36W - 220V AC low-cost high-frequency ballast demonstration board using the bipolar solution for power factor correction (PFC). The demonstration board is a complete reference system for a simple, cost-effective PFC for low-to-medium power high-frequency ballasts. The proposed bipolar PFC solution targets the low-cost high-frequency ballast market up to 80W, providing a simple and cost-effective solution without sacrificing total harmonic distortion (THD) and power factor (PF) levels. No additional integrated circuits (ICs) are required for the pulse-width modulation (PWM) signal, as the device uses only a power bipolar transistor and closed-loop feedback for duty cycle modulation and output power regulation. The active PFC solution with bipolar transistor adopts the boost topology and operates in discontinuous-conduction mode.
The STEVAL-ILB001V2 is a complete reference system designed for low-to-medium power high-frequency (HF) ballasts. It features a 36W power output operating from a 220 Vac input, utilizing a boost topology in discontinuous-conduction mode.
