A phase correction circuit, a phase correction method and an electric energy metering device are provided. The phase correction circuit includes a reference voltage circuit and a current correction circuit. The reference voltage circuit includes a first predetermined number of first delay D flip-flops and a first synchronization D flip-flop. The current correction circuit includes a second predetermined number of second delay D flip-flops, a second synchronization D flip-flop and a data selector. The data selector outputs a current signal of one of the second delay D flip-flops to the second synchronization D flip-flop. The second predetermined number is greater than or equal to the first predetermined number. In a case that the second predetermined number is equal to the first predetermined number, each of the second predetermined number and the first predetermined number is greater than 1.
