Design of a high-frequency inverter with high quality of output parameters along with reduction of its circuit complexity and cost is a topical task. In the paper, the main methods of the design of high-frequency inverters are analyzed. The principle of a magnetic switch operation based on high-frequency magnetic amplifiers, whose magnetic core is made of amorphous alloy with rectangular hysteresis loop, is described.

The paper suggests a new method of the design of the power inverter based on high-frequency magnetic amplifiers. The proposed circuitry allows obtaining the higher quality of output ac voltage, higher level of dynamic characteristics, reliability and efficiency of the inverter. It also provides low level of both radiative and conductive electromagnetic interferences. Besides, it allows the regulation of output ac voltage within a wide frequency range.

The use of the cores of different sizes for high-frequency magnetic amplifiers allows the realization of the inverters in a wide range of output powers (hundreds watts to 10 kilowatts).

Such power inverters can be used for uninterruptable power supplies, renewable power supplies and frequency regulation of electric drives.
