The proposed boost converter circuit using MAX732 IC will allow you to have a continuous voltage of 12V with a current of 150 or 200 mA. The input voltage can be between 4.5 to 9 V, which can be produced by three 1.5V batteries, for example. The circuit is quite simple, we will be using […]

What is IGBT: Working, Switching Characteristics, SOA, Gate Resistor, Formulas
IGBT stands for Insulated-gate-Bipolar-Transistor, a power semiconductor which includes the features of a MOSFET’s high speed, voltage dependent gate switching, and the minimal ON resistance (low saturation voltage) properties of a BJT. Figure 1 exhibits IGBT equivalent circuit, where a bipolar transistor works with a MOS gate architect, while the similar IGBT circuit is actually […]
0 to 50 V Adjustable Switching Power Supply Circuit using IC LM2576
In this article I will try to explain the construction of a 1.23 V to 50 V adjustable switching power supply circuit using the IC LM2576. The LM2576 family of regulators is a monolithic integrated circuit that performs all of the active operations of a step-down (buck) switching regulator. It offers exceptional line and load […]
IC 7805 Switching Regulator Circuit
Starting from a classical linear regulation, we will present the evolution towards a simple switching version. This will allow us to analyze the operation without going through the classical theoretical developments. In other words, a “practical” view of things. You can use the proposed design to significantly increase the backup time and efficiency of a […]
Industrial Valve Switching Detector Indicator Circuit
In this post I have explained a circuit idea which can be used for identifying the switching pattern of set of valves from a remote location, using just two wire from the valve sets to the indicator circuit at the distant location. The idea was requested by Mr. Andreas. Technical Specifications Here is another circuit […]
