Did you’ve ever had trouble catching or establishing connection with distant FM radio stations which were broadcasting programmes you wanted to listen to? Perhaps you’re aware there are a lot more faraway channels, further than the range of your FM receiver. Of course, you could purchase or construct a stronger FM tuner but, building a tunable FM […]

Adjustable RMS Modified Inverter Circuit using BJTs
A very interesting circuit of a RMS controlled modified sine wave inverter is discussed in this article which incorporates just ordinary transistors for the proposed implementations. The use of transistors typically makes the circuit easier to understand and more friendly with the new electronic enthusiasts. The inclusion of a PWM control in the circuit makes […]
Adjustable Switching Power Supply Circuit – 50 V, 2.5 Amps
The explained variable switching power supply circuit is designed around the integrated switch mode power supply controller device Type L4960 from SGS. The main features of this switching regulator can be summarized from the following data: Main Features Input voltage range: 9-50 VDC Output voltage variable from 5 to 40 V. Maximum accessible output current […]
How to Modify SMPS for Adjustable Current and Voltage Output
This article discusses a method through which any ready made SMPS can be converted into a variable current smps circuit using a few external jumper links. In one of the previous articles I have explained how to make a variable voltage SMPS circuit by employing a simple shunt regulators stage, in the present hack also […]
Adjustable 1.2V to100V DC Buck Converter Circuit using LM5164
Ok now we have this LM5164 chip, and we want to drop voltage from 100V down to let’s say 12V, right? But we also need 1A output so we need to design everything properly. Now this chip is cool because it has ultra-low quiescent current (IQ) so it does not waste much power when it […]
Adjustable 0-100V 50 Amp SMPS Circuit
The high power adjustable switching power supply is perfect for the purpose of laboratory work. The topology used to design the system is switching topology – half controlled bridge. Written and Submitted by: Dhrubajyoti Biswas Warning: The following circuit design works with a direct 220 V Mains AC without any isolation at the input side, […]
