Inverter of what this text produces see Fig. 1 Mainly by the MOS field effect tube, the ordinary power transformer forms. Its output power depends on the power of MOS field effect tube and power transformer, avoid the convoluted voltage transformer to wind, suit electronic fan`s spare time to adopt while making. Now introduce operating principle and fabrication process of this inverter.
Circuit DIY of the inverter (picture and text is explained in detail) - schematic

Adopt six inverters of CD4069 and form the signal generator of rectangular wave here. R1 is the compensating resistance in the circuit, used for improving the oscillating frequency caused by change of the mains voltage unstably. The vibration of the circuit charged and discharged to finish through the electric capacity C1. Its oscillating frequency is f =The maximum frequency of 1/2. 2 of the RC. diagramatic circuit is: fmax=1/2. 2* 3. 3* 103* 2. 2* 10-6=62. 6Hz; Minimum frequency fmin =1/2. 2* 4. 3* 103* 2. 2* 10-6=48. 0Hz. is because of the error of the component, actual value will have some the difference. Other surplus inverters, earth and avoid influencing other circuit in the input end. Because the maximum crest of signal voltage of vibration that the rectangular wave signal generator outputs is 0~5V, for drive the intersection of power and switching circuit fully, here show as in Fig. 3 from voltage amplification to 0~12 V. oscillating beacon with TR1, TR2. The test circuit is shown in Fig. 4. The input power used for test here adopts internal resistance low, with big discharge current generally greater than 100A 12V car storage battery, can offer for circuit the ones sufficient input power. Test is used and supported for the ordinary electric lamp. The method to test is to pass and change load magnitude, and the measurement input current, voltage and output voltage at this moment. The output voltage drops with...
