| Abstract |
The new simple configuration of the quasi-resonant circuit used to switching of the inverters' transistors with minimal power losses is presented. This circuit operates only at the moments of the transistors' commutation. The additional input capacitor and suitable simple method of the system control enables the bidirectional power flow and limits the overvoltage to the level 1,2 + 1,3 of source voltage. The theoretical study of the process of transistors' commutation in different possible conditions of work confirmed by laboratory investigations is the main subject of this article. |
