POWER CONVERTER PRE-CHARGE WITH LINE SYNCHRONIZATION
For power converter pre-charge with line synchronization, a method magnetizes a power transformer of a power converter with a supply voltage from a variable voltage variable frequency supply. The method pre-charges power cells of the power converter fed from the power transformer to a specified volt...

| description | For power converter pre-charge with line synchronization, a method magnetizes a power transformer of a power converter with a supply voltage from a variable voltage variable frequency supply. The method pre-charges power cells of the power converter fed from the power transformer to a specified voltage with the supply voltage. The method further modifies a primary amplitude, a primary phase, and a primary frequency of a primary winding of the power converter with the supply voltage to match a main amplitude, a main phase, and a main frequency of a main voltage of a main power source. In response to matching the primary amplitude, the primary phase, and the primary frequency to the main amplitude, the main phase, and the main frequency, the method connects the main power source to the power transformer. |
