The serial compensation rectifier, according to one aspect of the present invention, comprises: a compensation type power transformer connected to a single or multiple phase alternating-current power supply; a rectifier unit that rectifies a voltage, including said single or multiple phase alternating current voltage, transmitted via a first winding wire of said compensation type power transformer; a serial compensation inverter unit connected to a second winding wire of said compensation type power transformer; and a direct current capacitor connected to an output port of said serial compensation inverter unit. Output ports of said direct current capacitor and said rectifier unit are wired directly or via a direct current convertor, and said serial compensation inverter unit controls the power factor and the electric power of the input voltage of said alternating-current power transmitted via said compensation type power transformer, and said rectification unit enables the control of the rectified voltage.
