STEVAL-ILB001V2
36 W - 220 Vac low-cost HF ballast demonstration board using the bipolar solution for PFC
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 costeffective 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 closedloop 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.
