Myth vs reality: higher switching frequency in PV inverters
Stop guessing about PV inverter specs. This guide debunks myths on high switching frequency, revealing the truth about efficiency, size, and reliability for your solar system.
The frequency corresponding to the maximum output voltage of the inverter is called the basic frequency; b. When the output voltage of the frequency converter is equal to the rated voltage, the minimum output frequency is called the basic frequency. The fundamental frequency is represented by fBA.
Every inverter has its frequency limits, dictated by its design, components, and intended application. These limits define the range within which the inverter can operate safely and efficiently while maintaining compliance with relevant standards and regulations.
The low frequency inverters typically operate at ~60 Hz frequency. To produce a sine wave output, high-frequency inverters are used. These inverters use the pulse-width modification method: switching currents at high frequency, and for variable periods of time.
Exceeding these inverter frequency limits can lead to various undesirable consequences, including component stress, overheating, reduced system lifespan, and potential safety hazards.
