Description
The AC-Chopper is an application which has been developed for voltage regulation in an AC motor or AC load up to 300W. When connected to a motor or AC load, it allows the user to demonstrate smooth, silent, and efficient regulation with respect to triac solutions. The main applications of this reference design are AC asynchronous mono-phase motors like refrigerators, hydraulic pumps, fans, lamps, etc. ST Components ■ ST7FLITE05 : 8-bit MCU with single voltage flash memory, data EEPROM, ADC, timers, SPI ■ STGP7NC60H : N-channel 14A - 600V very fast PowerMESH™ IGBT ■ VIPer12ADIP: low power off line SMPS primary switches ■ L78L05A: positive voltage regulator ■ STTH108 : High voltage ultrafast rectifier ■ STTH3R06 : Turbo 2 ultrafast high voltage rectifier STEVAL-IHM006V1
