Useful in many geographic locations, solar-powered pumps are particularly advantageous in remote areas, where there may not be conventional power to provide ground water. The impressive CY8C27443 microcontroller-based Solar Pump Controller features a mixed-signal array that controls a three-phase motor drive to operate a submersible water pump directly from solar panels. The powerful PSoC microcontroller provides three-phase PWM generation, signal conditioning, over-current and fault protection, temperature monitoring, and constant voltage-to-frequency control. Additionally, the CY8C27443 MCU maximizes the power from the solar array. The result is a robust, low-cost, highly efficient controller.

Description: Pulse-width modulation (PWM), or pulse-duration modulation (PDM), is a modulation technique that conforms the width of the pulse, formally the pulse duration, based on modulator signal information. Although this modulation technique can be used to encode information for transmission, its main use is to allow the control of the power supplied to electrical devices, especially to inertial loads such as motors. In addition, PWM is one of the two principal algorithms used in photovoltaic solar battery chargers,[1] the other being MPPT.

Description: In this paper it is presented a detailed description
of the analog implementation of the control for a DC-AC
converter composed by a DC-DC Zeta converter and a low
frequency inverter. Using only analog components, it was
developed the MPPT technique based on linearization of solar
panel characteristic around the MPP, a feedforward control and
a robust PWM sine wave modulator. This simple and low cost
solution was designed to be used in grid connected rooftop
photovoltaic panels (PV). In scenery where an entire city area
could be used to generate extra power, reducing the necessity of
huge central power plants, module integrated inverters will play
an important role on grid connection of PV systems with high
reliability due to the high level of redundancy. The experimental
results show that this simple cost effective solution is able to
extract maximum power PVs with low current harmonic
