Claim of US Patent No. 10,342,144

1. A power supply with a staggered configuration comprising:a housing including a first sidewall and a second sidewall which are in parallel with a first direction, wherein an accommodation space is formed between the first sidewall and the second sidewall, wherein opposite ends of the housing along the first direction are a first end and a second end, respectively;
a first power supply module disposed inside of the accommodation space of the housing and between the first end and the second end of the housing;
a second power supply module disposed inside of the accommodation space of the housing and staggered with the first power supply module as well as between the first end and the second end of the housing; wherein
the first power supply module includes a first frontend power conversion unit and a first backend power conversion unit; the second power supply module includes a second frontend power conversion unit and a second backend power conversion unit; wherein the first frontend power conversion unit and the second backend power conversion unit are next to an inner side of the first sidewall, and the second frontend power conversion unit and the first backend power conversion unit are next to an inner side of the second sidewall;
a first power input port disposed at the first end of the housing and connected to an input of the first frontend power conversion unit;
a second power input port disposed at the first end of the housing and connected to an input of the second frontend power conversion unit;
a power output port disposed at the second end of the housing;
a first circuit board disposed inside of the accommodation space and on the first sidewall of the housing, wherein the first frontend power conversion unit and the second backend power conversion unit are mounted on the first circuit board;
a second circuit board disposed inside of the accommodation space and on the second sidewall of the housing, wherein the second frontend power conversion unit and the first backend power conversion unit are mounted on the second circuit board; and
a third circuit board disposed inside of the accommodation space of the housing and connected to the first circuit board and the second circuit board, wherein the power output port is mounted on the third circuit board and extends beyond the second end of the housing, the first frontend power conversion unit is connected to the first backend power conversion unit through the third circuit board, and the second frontend power conversion unit is connected to the second backend power conversion unit through the third circuit board.
