STEVAL-IHT001V1

Thermostat control demonstration board for refrigerators,

based on the ST7Lite39

Features

Description

The STEVAL-IHT001V1demonstration 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.
