Provided is a control method of a novel power factor compensation controller. A traditional power factor compensation controller is poor in reliability and low in measurement accuracy. The novel power factor compensation controller comprises a shell, the shell (1) is internally provided with a phase difference detection circuit A (5), a phase difference detection circuit B (17) and a phase difference detection circuit C (18), the phase difference detection circuit A, the phase difference detection circuit B and the phase difference detection circuit C are connected with a phase difference numerical computation circuit (7) which is connected to a main control CPU (8), the main control CPU feeds back to the phase difference detection circuit A, the phase difference detection circuit B and the phase difference detection circuit C through circuits, and the main control CPU is further connected with a phase power factor display circuit A (9), a phase power factor display circuit B (10) and a phase power factor display circuit C (11) through circuits. The control method is applied to the novel power factor compensation controller.
