强大的PSoC微控制器提供了三相PWM生成，信号调理，过电流和短路保护，温度监测，并不断的电压频率控制。此外，微控制器CY8C27443最大的电力来自太阳能电池阵列。这样做的结果是强大的，低成本，高效率的控制器。-Solar Pump Controller
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.

frequencycurrent-mode PWM controller. They are specially
designed for Off-Line and DC to DC converter applications
with minimum external components. These integrated
circuits feature a trimmed oscillator for precise duty cycle
control, a temperature compensated reference, high gain
error amplifier, current sensing comparator and a high
current totempole output for driving a Power MOSFET. The
UC3842 and UC3844 have UVLO thresholds of 16V (on)
and 10V (off). The UC3843 and UC3845 are 8.5V(on) and
7.9V (off). The UC3842 and UC3843 can operate within
100 duty cycle. The UC3844 and UC3845 can operate
