The mechanism of the inverter commutation is studied. The circuit is composed of two resistances instead of a transformer. Gate voltage is 2 V, and gate current 3 mA. Capacity of the commutation condenser is 20μF. The voltage of the commutation condenser is calculated and it is shown that the anode voltage of SCR becomes negative, then it cuts the anode current of SCR. When we use as a inverter, a transformer is used instead of two resistances. The transformer has three windings whose number of tums is 300 respectively. The range of the output altemating current is 0--4 A, and the maximum efficiency of the inverter, which converts DC energy to AC energy, reaches 75%. The range of the frequency of AC could bechanged from 20 to 300 c/s in our experiments.
