Both coils are coupled and provide positive feedback. As collector current grows it induces more base current. This process continues until the coil is saturated when base current ceases and the process is reversed. The process depends on the orientation of the turns of the coil so that they provide positive feedback. A couple of dots in that diagram are essential and missing although they can be deduced.could anyone explain how this inverter circuit works?
