Abstract:
1. An apparatus comprising: a conversion device to convert direct current (DC) power from a battery set into alternating current (AC) power, and a current transformer arrangement to generate a DC charging signal based on the AC power and provide the DC charging signal to the battery set; wherein the current transformer arrangement includes: a first current transformer operatively coupled to the conversion device to generate a first AC charging signal based on a first phase of the AC power; a bridge rectifier operatively coupled to the first current transformer to convert the first AC charging signal into a first DC charge; a second current transformer operatively coupled to the conversion device to generate a second AC charging signal based on a second phase of the AC power; and a second bridge rectifier operatively coupled to the second current transformer to convert the second AC charging signal into a second DC charge, wherein the DC charging signal includes the first and second DC charges.
