Some output frequencies of the inverter are closely related to voltage, power, and other factors. Here's a detailed breakdown:

1. Relationship between inverter output frequency and output voltage: The inverter’s output frequency is directly proportional to the output voltage. For example, when the frequency is adjusted from 50Hz to 30Hz, the measured output voltage drops to 232V. This means that at 60% of the rated frequency, the output voltage is also approximately 60% of the input voltage. This linear relationship ensures stable operation under varying load conditions.

2. Relationship between inverter output frequency and input power: The output frequency is proportional to the cube of the input power. If the output frequency decreases from 50Hz to 30Hz, the input power will drop significantly. For instance, if the motor's rated power is 100kW, the input power may reduce to around 21.6kW. This cubic relationship highlights the importance of proper power management in inverter systems.

3. Relationship between inverter output frequency and input current: Similarly, the output frequency is proportional to the cube of the input current. When the frequency is reduced from 50Hz to 30Hz, the input current will also decrease accordingly. For example, if the motor's rated current is 200A, the input current might drop to about 43.2A. This shows how current and frequency are interrelated in inverter operations.

Understanding these relationships is crucial for optimizing inverter performance, ensuring safe operation, and improving system efficiency. Whether you're working on industrial equipment or home electronics, knowing how these parameters interact can help you make better decisions and avoid potential issues.
