Abstract
The purpose of this paper was to design and build an automatic high efficiency photovoltaic powered boat water pump system using boost DC-DC converter as switching charger, this system consisted of a solar array, a switching battery charger based on boost DC-DC converter, a battery and small water pump. The solar array had a specification as 44 watts of output power, 12-22 volts of output DC voltage, and 2- of output DC current. The output power of solar array was the input power for boost DC-DC converter as the switching charger. To control the boost converter, the pulse width modulation (PWM) was applied. The water pump was controlled by a microcontroller PIC 186627. When the water amount reaches the specified level, a sensor will send the signal to the microcontroller for controlling a relay to drive a motor in the water pump.
To verify the proposed pump system, the prototype of water pump for small boat was built to experiment. From the results, to stabilize the output vo
