Abstract
Techniques that eliminate the need for a dedicated pre-charge resistor by using the main power path of the AC/DC, DC/DC, or DC/AC converter. By eliminating the pre-charge resistor, the techniques increase the maximum allowable current rating of the converter as well as increase the impedance and inductance of the converter.
