Ham radio power supply circuit with RFI elimination
This is the Ham radio power supply circuit with RFI elimination for Amateur radio. A typically Radio transmitters use High-frequency transistors as current driver so can cause very severe electromagnetic. Therefore, The power supply must be able to make the current higher than 10A. Figure 1 the schematic diagram RFI elimination …
10V to 350V Adjustable Regulator DC Power Supply
Here is an adjustable regulator DC power supply circuit that can be provided the output high voltage is 10V to 350V. It use the transistor is based so we use often use them. Now, a transistor can tolerate more high pressure. For example; in this circuit we will use number …
0-30V,0-2A adjustable  voltage and current regulator
This is the 0-30V,0-2A adjustable voltage and current regulator that developed from the cheap adjustable 0-30V 2A Laboratory DC Power Supply project using LM723 is used widely, for a long time. This project can control the amount of current flow is maximum. We modified the circuit as circuit in Figure …
