Title:
RAPID CURRENT AMPLIFICATION SYSTEM AND METHOD BASED ON POWER AMPLIFIER
Document Type and Number:
WIPO Patent Application WO/2022/028066
Kind Code:
A1
Abstract:
A rapid current amplification system and method based on a power amplifier. The system comprises a main power module, a main control module, and rapid current amplification modules. The main power module is connected to the main control module. Several rapid current amplification modules are connected in parallel and connected to the main power module. Each group of rapid current amplification modules comprises two signal analysis processing modules and a load. The two signal analysis processing modules are connected in parallel. The input ends of the signal analysis processing modules are connected to the main power module, and the output ends are connected to the load. The operating state of the load is determined, and the switching frequency of the current is changed, so that the current output of the current amplifier is maintained at a peak value. The system has the advantages of improving the power factor by changing the current amplification mode, i.e., amplifying fundamental current by means of a power amplifier. Using multiple 5-10 KW power modules connected in parallel as the main power module improves the stability of the power supply. In addition, a low-power power supply has a relatively high switching frequency, thereby providing a sufficient inductive load on the current transformer.
