Texas InstrumentsTMDSHVBLPFCKITSistema integrato, schede e kit di sviluppo

The High Voltage Bridgeless PFC Developer's Kit uses a Piccolo microcontroller to control a 300W high efficiency BRIDGELESS PFC stage. Additions to this EVM include a fast Feed Forward (FF) control loop based on half cycle RMS measurement of the AC line. This control loop offers designers a faster response to input voltage transients without sacrificing Power Factor. This EVM is designed to operate off a universal ac line input of 85V to 265V and provides a regulated 390V dc output, with the option to power the digital circuitry from an external power supply. This kit can be used as a stand-along PFC development kit or in conjunction with the complimentary secondary side TMDSHVRESLLCKIT or TMDSHVPSFBKIT evaluation boards to build a complete PFC correct AC to high efficiency DC topology. The kit includes isolated USB JTAG emulation. Software and hardware documentation for the kit are included in controlSUITE.
