Based on sufficient study on the output characteristics of the solar cell, in this paper, a kind of simulator simulating the output of the solar cell, using the single-chip computer (SCM) and DC/DC inverter is designed. This simulator can simulate the output of the solar cell, completely according to the working characteristic curve given by the solar cell. Thereby it can eliminate the outside influence...
In order to control vegetable diseases and insect pests in the vegetable base, the ozonizer of SCM controlled is designed in this paper. The paper provides the system architecture of ozonizer and the IGBT inverter power supply. It also introduces the simulation design of control system by proteus, and gives the kind of problems and solutions occurred by ozonizer installation. The production of ozonizer...
In this paper, to achieve high-precision steady state waveform and fast dynamic performance, a new control method is introduced, namely, a two-tier structure, the traditional digital PID controller and repetitive controller working in parallel. We name it as hybrid controller. Response speed between the two kinds of control methods is different and the time is decoupled. This control method can restrain...
Based on the small-signal model of the half-bridge circuit, the double close loops control system of the inverter arc welding power supply was designed under the average current control mode. For the control system's voltage and current controllers, the loop gains, angular frequencies of zeros and poles were determined. The simulation model of the designed double close loops control system was established...
