Single Phase Variable Frequency Drive VFD Circuit
In this post I have explained a single phase variable frequency drive circuit or a VFD circuit for controlling AC motor sped without affecting their operational specifications. What is a VFD Motors and other similar inductive loads specifically do not “like” operating with frequencies that might be not within their manufacturing specs, and tend to […]
Non Contact AC Phase Detector Circuit [Tested]
The circuit discussed in this article is of a non-contact mains AC field detector which displays the presence of a mains AC field from a distance of more an 6 inches. Locating Fault in AC Lines without Physical Contact The circuit can be used for locating faults in house wiring without the need of making […]
3-Phase Signal Generator Circuit using Opamp
Many a times we find it crucial and handy to possess a true three phase signal for evaluating many different electronic configurations such three phase inverters, three phase motors, converters etc. Since it’s not so easy to incorporate single phase to three phase conversion quickly we find this particular implementation difficult to acquire and enforce. […]
Transistor based 3 Phase Sine Wave Generator Circuit
In this post I have explained a very simple 3-phase sine wave generator circuit, using only three bipolar transistors and a few passive components for initiating the desired three phase output. How it Works Referring to the 3 phase sine wave generator circuit we can see three identical transistor stages configured in a cross coupled […]
3 phase Solar Submersible Pump Inverter Circuit
In this post I have explained a simple 3 phase solar submersible pump inverter circuit which can be made by configuring a few ICs and a few power devices. The idea was requested by Mr. Lufono and Mr. Sami. Circuit Objectives and Requirements First of all i must say thanks to you and Mr. Lufono, […]
