Title:
SMART THYRISTOR VOLTAGE CONVERSION CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2020/252968
Kind Code:
A1
Abstract:
A smart thyristor voltage conversion circuit, comprising a first thyristor (20), a first alternating-current output driving circuit (60), and a main control circuit (80). One end of the first thyristor (20) is connected to an alternating-current input end, and the other end of the first thyristor (20) is connected to a first alternating-current output end. The main control circuit (80) is used for controlling the first alternating-current output driving circuit (60) to drive turn-on of the first thyristor (20) to directly output input alternating current so as to output first alternating current, or used for controlling the first alternating-current output driving circuit (60) to drive alternate turn-on and turn-off of the first thyristor (20) to output the input alternating current in a step-down manner so as to output the first alternating current. For example, an input alternating current of 220 V is stepped down by the first thyristor (20) and converted to 110V alternating current, or an input alternating current of 110V is directly output by means of the first thyristor (20) to adapt to European and American power supplies, etc. The overall circuit is relatively simple, manufacturing costs are low, and the output voltage value can be intelligently adjusted.
