Giải pháp tăng biên độ điện áp xoay chiều và ổn áp xoay chiều không sử dụng biến áp

Increasing or decreasing the alternating voltages of grid electricity (50Hz) is known as

the use of transformers, in this paper we present three solutions for increasing the AC voltage

without the transformer: Duplicating the alternating voltage amplitude, increasing the

amplitude of the AC voltage with a coefficient of continuous increase from 1.0 to 2.0, and

Stabilizing the AC voltage without transformer. With common components in the Vietnamese

market, it is possible to design the equipment to increase the amplitude of AC voltage with the

maximum capacity of 2kVA. By not using a transformer, the advantage of this type of amplifier

is that it is compact and light.
