In general, the water pump machine used in households is a centrifugal water pump type driven by a 1-phase permanent-split-capacitor induction motor or abbreviated as PSC motor. In the use of driving a water pump using solar power, a 3-phase cage rotor induction motor must be driven by a 3-phase alternating voltage. A 1-phase permanent-split-capacitor induction motor or abbreviated as PSC motor…
A power supply circuit that produces a lot of output is needed by electronic systems that work with several voltage levels. An example is a control circuit that controls a 3-phase inverter, where the control circuit uses several integrated circuits (IC) which must be supplied by a power supply. isolated from one another. The power supply circuit that will be made gets power input from solar pan…
A three-phase induction motor is a type of AC (Alternating Current) motor that is input by alternating current. When driving a water pump using solar power, a 3-phase cage rotor induction motor must be driven by a 3-phase alternating electric voltage. For this purpose, a power converter is needed which will convert the direct electricity produced by the solar panels into 3-phase alternating ele…
