A generator designed for pulse-frequency power supply of high-voltage technological installations is considered. The generator is connected to an external source with a relatively low constant voltage and power. The generator contains a switch constructed on an IGBT transistor and a transformer as an energy-storage device with a diode "back" connected to the secondary winding and an output capacitor. The operability of the generator model has been experimentally tested, a significant reduction in switching overvoltages and unwanted surges of currents has been obtained, which reduces the likelihood of generator equipment failure. A calculation method has been developed for single-pulse charging of the output capacitor, which makes it possible to determine the resistances, inductances, and capacitances of the generator elements and its voltages, currents, power and efficiency with the active-inductive nature of the load. The calculation method can be used in the design of generators with a power of up to 5 kW and a pulse repetition rate of up to 100 Hz with a pulse energy of up to 50 J. The reliability of the calculation method has been confirmed experimentally. [ABSTRACT FROM AUTHOR] |
