      A simple and practical triode inverter circuit

      Capacitors C1 and C2 use polyester capacitors, and transistors BG1-BG5 can use 9013: 40V0.1A.

      0.5W, BG6-BG7 can use field effect transistor IRF150: 100V40A150W0.055 ohm. For the winding of transformer B, please refer to the design calculation method of the inverter and debugging under amateur conditions; without connecting the power tube first, measure the voltage of point A and point B to the ground, and use R1 or R2 to set the voltage of the two points A and B. This is necessary so that the output square wave can be symmetrical and the quiescent current can be minimized. Pay attention to the following matters during installation: When welding BG6 and BG7, use a grounded soldering iron or cut off the power supply before welding. Large currents should be connected with thick wires with a diameter of 2.5MM, and the connections should be as short as possible. The battery voltage is 12V and the capacity is 12AH. The power tube should be equipped with appropriate heat sinks, such as 100*100*3MM aluminum plate for heat dissipation. If you want power, power tubes of the same type should be used in parallel, corresponding to the power of the transformer.
