Solar PV systems (utility-scale farms, rooftop panels, solar trackers) require components that maximize energy harvest, withstand outdoor conditions, and ensure grid compatibility. Key components include:
PV Inverters:
Power Semiconductors: Silicon Carbide (SiC) MOSFETs (e.g., Wolfspeed C3M0065090J, 900V, 65mΩ) and Gallium Nitride (GaN) HEMTs (e.g., Navitas NV6117, 650V, 15mΩ)—enable inverter efficiency >98.5% at full load, reducing switching losses by 60% vs. silicon IGBTs and supporting high-frequency operation (20kHz–50kHz) for compact designs.
Inverter Controllers: Texas Instruments TMS320F28379D (200MHz DSP, integrated PWM generators)—optimizes maximum power point tracking (MPPT) with >99% efficiency, adapting to varying sunlight conditions (e.g., cloud cover) in <100ms.
Solar Trackers & Monitoring:
Position Sensors: Renesas RA8875 (angle sensor, ±0.1° accuracy)—enables dual-axis solar trackers to follow the sun’s trajectory, increasing energy yield by 20–30% vs. fixed panels.
Data Acquisition ICs: Analog Devices ADE7878 (energy metering IC, 0.1% accuracy)—measures AC/DC power flow, voltage, and current, supporting remote monitoring via Modbus/TCP or LoRa.
Protection & Safety:
Surge Protectors: Littelfuse SP3520CA (10kV/20kA)—shields PV arrays from lightning strikes and voltage transients, complying with IEC 61000-4-5.
Isolation Transformers: Vicor VI-260 (isolation voltage 3kV)—prevents ground faults and ensures compliance with IEC 61727 (safety requirements for PV systems).
