Figure 1. DOE proposed regulations vs. Level V performance for a 5V output EPS
The need to reduce active-mode power consumption is somewhat obvious. What has not been so obvious is the need to minimize power drain in standby and no-load when products are essentially doing nothing. Several studies have been performed worldwide to quantify this consumption by domestic equipment

Figure 1. Circuit diagram of the ADP2441 step-down switching regulator in a 24V nominal to 3.3V conversion
Industrial power supplies need to have very high efficiency today and often times need to be highly compact. In combination with the typical 24V rail available, many solutions utilize a switching regulator rated for 36V Vin max. Unfortunately most solutions available are non-synchronous switching regulators

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
