Figure 1: Basic circuit configuration of inverters
At least two power reactors are needed for solar inverters: one in the boost converter (step-up chopper) and one at the ouput of the inverter for EMC filtering. Besides the IGBTs, the losses in the reactors are a major determining factor of the overall efficiency of the inverter
Low-loss and high saturation flux density core materials in reactors and transformers are a key determining factor for the efficiency of inverters.
The new TDK PE90 ferrite is a cutting-edge material that minimizes reactor losses in the step-up chopper and smoothing circuits of inverters
