3.1 Perturb and Observe [5]วิธีนี้เ

3.1 Perturb and Observe [5]This method is an easy way not a complicated period, using the comparison of photovoltaic power in the current period to the period before. If the rate of change of electric power are positive, the system will adjust the direction of the voltage (increase or decrease voltage) according to the directions, and if the rate of change of negative power, the system will adjust the direction of the pressure against the direction was to rush toward the maximum power supply. By Duty cycle in order to drive the gate Work process: Figure 3

3.1 Perturb and Observe [5]
This method is a simple discrete functions using the power of solar cells in the current period and prior periods. If the rate of change of power is positive, the system will adjust the direction of pressure. (Increase or decrease pressure), the original direction. And if the rate of change of power is negative, the system adjusts the voltage to run counter to the original direction toward the maximum power point. Duty cycle is configured to drive the gate process is shown in Figure 3.

.This method is simple, no complicated working period by comparison of the solar cell power in current period and period.(increase or decrease) in the direction of the original pressure and if the rate of electric power is negative pressure adjustable system direction of contrary to the original direction to run the point of paying is maximum. By using Duty cycle to drive the gate.3
