Method and apparatus for control of input current of high-current and high-voltage applications

An inrush current controller for controlling inrush current during primary and secondary inrush current phases from a power source to a load, comprising:

• a first electronic switch connected between said power source and said load;
• a second electronic switch connected in series with a resistive device, wherein the series connected combination is connected between said power source and said load;
• a pulse generator which is configured to provide a pulse of a predetermined length that corresponds to the primary inrush current phase;
• and
• control circuitry connected to said pulse generator, wherein said control circuitry, at the commencement of a pulse from said pulse generator, is configured to enable said second electronic switch and, at the cessation of said pulse, is configured to apply a test condition and enable said first electronic switch during the secondary inrush current phase after the test condition is met.
