STMicroelectronics Altair05-800 | Demoboard STEVAL-IPFC01V1 3 kW interleaved PFC

Beschreibung

The STEVAL-IPFC01V1 3 kW interleaved PFC kit is based on the STNRGPF01 digital controller and includes a separate power board, control board and adapter board. The STNRGPF01 is a digital configurable ASIC developed by STMicroelectronics, which can drive up to three channels in an interleaved PFC for industrial applications and is designed to meet the IEC 61000-3-2 standard for electrical equipment.The STNRGPF01 digital controller on the control board implements mixed signal (analog/digital) average current mode control in CCM at fixed frequency. The analog section ensures cycle-by-cycle current regulation, while digital control manages the non-time critical operations. You can use the eDesignSuite software available on the ST website to configure the STNRGPF01 for specific applications.Key Features 3 kW interleaved PFC kit with following boards: STEVAL-IPFC01P1 power board STEVAL-IPFC01C1 control board STEVAL-IPFC01A1 adapter board Input voltage range: 90 to 265 VAC Line frequency range: 47 to 63 Hz Maximum output power: 3 kW at 230 V Output voltage: 400 V Power factor: > 0.98 at 20% load Total Harmonic Distortion: <5% at 20% load Mixed-signal average current mode control, CCM fixed frequency operation Switching Frequency: 111 kHz Cycle-by-cycle regulation (analog current control loop) Input voltage and load feed-forwards Phase shedding Burst-mode operation Overvoltage protection Thermal protection Status indicator LEDs Inrush current limiter function Cooling function
