It will be shown how the power losses in the coil core increase with the switching frequency. The serial equivalent resistance of the inverter depends on the power losses in the coil core as well as the dynamic and static losses on the switching transistors.
For applications that require high power quality and are sensitive to the electromagnetic environment, you can choose an Low Frequency inverter; while for applications that require portability, high efficiency and fast response, High frequency inverters are more advantageous.
In today''s world, inverters play a vital role in various applications, such as home solar power system, inverter for office use, inverter for van, etc. Central to their operation is the concept of an inverter frequency, which determines the rate at which the current alternates direction.
This paper aims to show how the switching frequency influences the properties of the digitally controlled voltage source inverter (VSI). The measurements of the Bode plots of the inverter are shown and discussed to present the existing signal delays and power conversion efficiency, depending on the switching/sampling frequency.
