Suppose you have a 10 amp power supply and you want to confirm the 10 amp output through some sort of dummy load which can absorb 10 amp current. For […]
IC 7805 Variable Power Supply Circuit [5V to 15V]
Although, a 7805 IC is mostly used as a fixed 5 V voltage regulator, it is possible to configure a 7805 IC to produce a variable output from 5 V […]
Higher Variable Output Voltage from IC 7812
You may have often wondered whether it was feasible to get higher voltages than 12 V from a 7812 IC? In this short post we learn how to configure the […]
IC 741 Power Supply Circuits
In this post we learn how to make simple yet fully stabilized and regulated, variable power supply circuits using the IC 741 op amp. Three versions of the 741 power […]
SCR Voltage Regulator Circuit
In this post we will discuss how to build a highly efficient voltage regulator circuit using an SCR and some other external components. This SCR voltage regulator circuit being a […]
DC to DC Converter Circuits using SG3524 [Buck, Boost Designs]
A DC to DC converter is basically a switch-mode power supply, designed to work either as a boost-converter to step-up a low voltage DC to a higher voltage DC, or […]
