AC-DC converters are widely used in both consumer electronics and industrial equipment. The LK1301-9ERG AC-DC converter is an advanced, high-efficiency device designed for use in power supplies, solar inverters, medical equipment and other applications. This AC-DC converter is suitable for the most demanding applications and can provide high-efficiency power conversion.

The LK1301-9ERG AC-DC converter is designed with advanced circuit topology and features superior energy efficiency, maximum resistance to surge voltages, and its high output power provides extended operating life. The converter is designed to support input frequencies up to 400Hz and has the ability to work with a very wide range of input voltages from 44 to 264VAC.

The LK1301-9ERG AC-DC converter consists of a switching power conversion stage, a high frequency transformer, and a power factor correction circuit. The switching power conversion stage is executed by a half bridge resonant circuit. This circuit is driven by a pulse-width modulator operating at a fixed frequency, which is determined by the input voltage. The transformer rectifies the output of the switching power conversion stage and produces the DC output voltage.

The power factor correction (PFC) circuit consists of two stages. The first stage is an inductor connected in series with the half bridge rectifier and a capacitor connected in parallel with the rectifier. This circuit is responsible for harmonizing the input current with the sine wave of the input voltage and reducing power dissipation in the high frequency transformer. The second stage uses a boost converter to rectify the output of the PFC circuit which is then filtered and regulated to produce the DC output voltage.

The LK1301-9ERG AC-DC converter is designed for use in a wide range of applications, including industrial equipment, home appliances, medical devices, and solar inverters. This advanced converter provides high efficiency power conversion, maximum resistance to surge voltages, and extended operating life. Its high input frequency capability and wide input voltage range make it the ideal choice for a wide range of applications.
