Inverter Schematics


Posted on Feb 6, 2014

A small bias on the bases of Q1 and Q2 via R1 and R2, assists in `starting` This gives each transistor`s base a small forward bias, so that both transistors tend to conduct when the circuit is first switched on [the base voltage on each transistor is zero when circuit is first switched on, so the small forward biasing thru R1 and R2 results in an

above zero voltage at each base]. Use of IC timing [clock] circuitry, along with quality core materials for the transformers and possibly JFET`s wil increase the accuracy, and decrease the losses, making the Inverter more efficient. The transformers` coils and cores will need to be large, since the output Hz required is 60Hz. If this was part of a DC to DC converter, or if this was used for Frequency Inversion [input = low Hz, output = High Hz], then the clock circuitry can be set for a higher Hz. like 40KHz [or what ever the output Hz will be]. Being up in that range will reduce the size of the transformers dramatically - which also increases efficiency by decreasing core losses, winding losses and losses from heat [winding resistance, core`s reluctance, etc. ].
