Level Meter Circuits SPM-3 WG
Here are three circuits from the manual. The design is entirely on discrete devices like transistors, diodes and zeners. Studying these designs will reinforce your basics. It is easy to make things work with...
Diode Reverse Bias Leakage Tester
This is a Test arrangement for Leakage Testing of Diodes on Reverse Bias. The leakage current indicates the ability of the diode to withstand higher voltages. An AutoTransformer or Variac can be used to...
Voltage Doublers and Multipliers
Voltage multipliers are used to obtain low current high voltage, from an existing AC Source. Step up transformers can be used, but the insulation problems and care that has to be taken for HV...
