The efficiency of an inverter refers to the ratio of AC power output to DC power input. High-frequency inverters generally have higher efficiency than low-frequency inverters. This is because the higher operating frequency reduces the size of transformers, capacitors, and other components, leading to lower power losses.
Below 10-15% of power output, efficiency is quite low. At high output power, the efficiency is steadily high with some small variations. The behavior in Figure 11.8 partially results from the fact that stand-by losses for an inverter are the same for all output power levels, so the efficiency at lower outputs is affected more.
The advantages of high frequency inverter are: light weight, small size, small standby power and high efficiency. The working frequency of high-frequency transformers is generally above 1KHz, even tens or hundreds of KHz.
High-frequency inverters generally have higher efficiency than low-frequency inverters. This is because the higher operating frequency reduces the size of transformers, capacitors, and other components, leading to lower power losses. Low-frequency inverters have lower efficiency due to higher losses in magnetic components and switching devices.
The efficiency of an inverter indicates how much DC power is converted to AC power. Some of the power can be lost as heat, and also some stand-by power is consumed for keeping the inverter in powered mode. The general efficiency formula is: ηinv = PAC PDC η i n v = P A C P D C
Typical generic inverter efficiency curve. Below 10-15% of power output, efficiency is quite low. At high output power, the efficiency is steadily high with some small variations.
