| Using conventional boost converter in photovoltaic system as the interface between the photovoltaic panel and the consumer is widely practiced. In this paper, instead of using conventional boost converter, the three-level boost converter (TLBC) has been used. The advantages of TL converters include reduced voltage stress of the switches, reduced filter size, and improved dynamic response. However, the capacitor voltages may be different due to their mismatched equivalent series resistance, their mismatched capacitance, and the mismatched conducting time of the corresponding switches. This paper investigates the output control TLB converter for dc drive applications. A PI controller method is applied for adjusting the output voltage and internal generated voltage . That Kp and Ki gains set as well and output is very smooth and free of oscillation generated. On the other hand, the voltage can be controlled to transmit dc motor. A P controller method is then used for the individual capacitors voltage balancing. At the absence of control, voltage capacitors are also many differences. Simulation results show the high dynamic performance of the controller in adjusting the capacitors’ voltages and output control TLB converter. | ||
