Description
The STEVAL-IHT001V1demonstration board is a complete reference system for a simple costeffective PFC (power factor corrector) using bipolar transistors and is intended for low-tomedium 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. STEVAL-IHT001V1
