Photovoltaic power may vary depending on the various solar cell has an optimal generating point to be able to get the maximum power tracking, in order to get the more power recovery on the switching control system. However the V-I characteristics of the solar array at the frequency have hysteresis, in such high frequency region the conventional controller based on no hysteresis can not be responsible for control of the photovoltaic power system. Therefore, in this paper we proposed a maximum power tracking technique to improve the operation in the region of high frequency[5KHz-30KHz] with added C-R differential circuit for zero cross switching. The distinguishing characteristics of this method is to be controlled by the estimated values of resistive current and sensed photovoltaic terminal voltage do not depend on the operating frequency. the experimental result of the power system is controlled by the proposed sampling.

In this paper, we applied the Utility Interactive Photovoltaic-Wind Hybrid Generation System for stock raising waste disposal system. For the power consumption reduction of proposed system, we used the electromotive control system. And structure of sewage disposal tank is half-underground and slope a roop to raise thermal efficiency. Therefore, A period of procrss is able to reduce. So as to verify the propriety of proposed system, we made a Pilot Plant and examined the system.

Due to the development of information communication field not only the industrial electric machinrye but also the electronic·communication machinry including the computer and satelite, the interests for SMPS are increasing. Thus the low loss converter which can be operated in high speed switching is require. In this paper, a control strategy for the constant output power of resonant FB DC-DC converter in variable input voltage is proposed. The proposed control of system is I-PD type control applying type 1 digital system. The output voltage tracks the reference without any steady state error even in variable input voltage. The validity of proposed control strategy is verified by simulations using PSIM.

A new simple control method for active power filter, which can realize the complete compensation of harmonics is proposed. In the proposed scheme, a model-based digital current control strategy is presented. The Proposed control system is designed and implemented in a form referred to as Internal Model Control structure. In the proposed control algorithm, overshoots and oscillations due to the computation time delay is prevented by explicit incorporating of the delay in the controller transfer function. In addition, a new compensating current reference generator employing resonance model implemented by a DSP(Digital Signal Processor) is introduced. Resonance Model has an infinite gain at resonant frequency, and it exhibits a band-pass filter. Consequently, the difference between the instantaneous load current and the output of this model is the current reference signal for the harmonic compensation.
