description The invention discloses a small wind machine maximum power tracing device and method. The device comprises an MTTP processor, a PWM controller and a DC/DC electrical energy conversion circuit. The MTTP processor is connected with a small wind machine and the PWM controller. The output power and the angular speed of the small wind machine are collected, according to the collected output power and the angular speed of three adjacent working points, the corresponding area ratio and output power difference value are obtained, and then disturbance step length variation is obtained and is transmitted to the PWM controller. The PWM controller is connected with the DC/DC electrical energy conversion circuit and compares the disturbance step length variation with PWM carrier signals, and PWM control signals are generated. The DC/DC electrical energy conversion circuit is connected with a load and is used for receiving the PWM control signals, output voltage and load power are adjusted in real time, and maximum power t
