The Science Behind Voltage Sampling in Inverters

Inverters act as the "translators" between DC power sources (like solar panels) and AC grids. But how do they measure voltage accurately? Let''s break it down:

Core Sampling Methods

• PWM (Pulse Width Modulation) Sampling: Uses rapid switching to create voltage pulses matching grid frequency
• Analog-to-Digital Conversion: Converts continuous signals into digital values for microcontroller processing
• Isolated Measurement: Optical or magnetic isolation protects sensitive components from high voltages

Why Voltage Sampling Matters in Real-World Applications

Consider this 2023 case study from a 50MW solar farm:

Sampling Rate	Energy Conversion Efficiency	System Downtime
10 kHz	94.2%	3.7%
