In this post we discuss the datasheet, and the pinout specification of the IC STGIPN3H60 from ST microelectronics, which is perhaps the slimmest and the smartest 3-phase IGBT driver IC featuring in-built IGBTs, rated to work with 600V DC bus and upto 3 amp current, that’s equivalent to almost 1800 VA handling power. 3-Phase IGBT Driver … Read moreCompact 3-Phase IGBT Driver IC STGIPN3H60 – Datasheet, Pinout
The post explains 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, I have many … Read more3 phase Solar Submersible Pump Inverter Circuit
In this post we discuss the making of a simple 3 phase induction motor speed controller circuit, which can be also applied for a single phase induction motor or literally for any type of AC motor. When it comes to controlling the speed of induction motors, normally matrix converters are employed, involving many complex stages … Read more3 Phase Induction Motor Speed Controller Circuit
The post explains a very simple bipolar transistor based 3-phase sine wave generator circuit, only three to be precise 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 … Read moreTransistor based 3 Phase Sine Wave Generator Circuit
