Description: 基于STM8系列单片机的DALI总线协议开发包（C语言程序）。单片机STM8S105，DALI总线从机程序。-DALI slave library comes with simple application example (DALI slave device). It was
designed (and tested) for use with this evaluation hardware: STM8S Discovery board (see
UM0817- STM8S Discovery User manual on www.st.com/mcu) together with DALI
transceiver board. Application example controls the luminance of the on-board LED diode.
Light intensity is controlled by PWM method using built-in Timer. As DALI master device
can be used ST7DALI evaluation kit (board and PC software- see www.st.com/mcu) or some
commercial DALI controller (e.g. from Osram).

Description: Independent control of active and reactive power without any needs for extra
compensating equipment.
With PWM, VSC-HVDC o® ers the possibility to control both active and reactive
power independently . While the transmitted active power is kept constant the
reactive power controller can automatically control the voltage in the ac-network.
Reactive power generation and consumption of a VSC-HVDC converter can be
used for compensating the needs of the connected network within the rating of a
converter.
