In this episode of "Testing circuits I found on the Internet", I will be having a look at a popular inverter schematic I found on google images. The design uses an astable multivibrator in order to pull current alternately through a transformer and thus create a high AC voltage on its output side. A lot of DIY inverters use this functional principle. That is why I will build up the schematic, properly test the circuit and show you what problems it comes with that you can more or less easily fix. Let's get started!
