ประโยค
- ตัวอย่างการใช้เพิ่มเติม: 1 2
- Dc - ac converter
- Comparing with the ac - dc - ac converter , the commutation process of a matrix converter ( mc ) is more complicated due to having no natural free - wheeling paths
- On the bases of detailing the control theory and circuit of dc - ac converter , this paper introduces the fuzzy logic theory into the control of the digital pwm converter . in order to realize the control strategy , intel high performance micro controller 80c196kc , the kernel of the intelligent controller are purposed
- First , variable speed constant frequency wind energy convertion theory is described in this paper , then presents a review on the development of wind turbines control and the main types of generator and static converters used to interface variable speed wind turbines to the electric grid . then discuss main circuit constructure and advantage of direct drive wind energy conversion system and introduce pitch - control method for wind power traction and electric power stability . simply aerodynamic characteristic of the turbine is analysised and permanent magnet synchnonous generator math model is established . to convert the variable frequency electricity into utility grid , back to back four - quadrant pwm - vsi is used and three typies of control strategy is presented to capture the maximum wind energy and transmit energy . then simulation is implemented to test the control strategy . in the following chapter a simple ac - dc - ac converter with a dc - dc boosting chopper is proposed to transmit the wind energy into electricity energy and two control strategy is presented
- The steady state and transient characteristics of the aceg system are simulated , the harmonics of the emf and stator current and rotor current as well as mc ' s input current are researched . the operation characteristics of aceg with mc as an exciter are compared to those of aceg with ac - dc - ac converter and cycloconverter as an exciter . the results in this thesis will be helpful to the design of the aceg excitation control system
