The model used for creating the reference voltage is shown in Fig. 4. First, photovoltaic output current (Ipv) and output voltage (Vpv) are passed through a first order low pass filter with a magnitude of G = 1 and a time constant of T = 0.01 seconds in order to filter out the high frequency components or harmonics from these signals as shown in Fig. 5 and Fig. 6. The filtered current and voltage signals (Ipv_F and Vpv_F) are then fed into the MPPT control block that uses the Incremental Conductance Tracking Algorithm. An algorithm that is based on the fact the slope of the PV array power curve shown in Fig. 7 is zero at the Maximum Power Point (MPP), positive on the left of the MPP, and negative on the right. The MPP can thus be tracked by comparing the instantaneous conductance (I/V) to the incremental conductance (∆ I/∆ V) [11] as in (1):

使用波模控制的直接转矩控制构建的系统，给出了相应的仿真模型及结果。(Wave mode control using the direct torque control system is built, gives the corresponding simulation model and results.)

by ankush laddha。This system is active front end rectifier. It keeps the DC link at reference value, 400V in this case, even if load is suddenly changes. Also power factor is controllable so can act as STATCOM too. Control is based on synchronous frame theory and 2-level inverter is switched using Sine triangle PWM technique.(This system is active front end rectifier.
