Abstract of the Disclosure A series-type independent inverter comprising a bridge network that includes silicon controlled rectifiers, the bridge network having an a.c. diagonal provided with a cir- cuit comprised of LC-elements, and having a d.c. diagonal provided with a coupling capacitor, and also comprising at least one uncontrolled semiconductor rectifier adapted to limit the voltage across the silicon controlled rectifiers. The inverter includes a saturated ferromagnetic element with a polarized magnetic circuit and with a primary winding in- serted in the d.c. diagonal of the bridge network and adap- ted to form together with the latter a ferroresonance cir- cuit, and also includes a filter tuned to a frequency that is a multiple of the input frequency of the saturated ferro- magnetic element and connected to the secondary winding of the element. The inverter of the invention makes it possible to in- crease the output voltage frequency in wide limits, while maintaining its efficiency as well as the parameters of its silicon controlled rectifiers at a higher level. In addi- tion, the inverter of the invention offers normal operation when the load resistance varies from zero to infinity.
