Title:
NOVEL MUTUAL-INDUCTANCE CONTACTLESS CURRENT STARTER FOR COMMERCIAL REFRIGERATION COMPRESSOR MOTOR
Document Type and Number:
WIPO Patent Application WO/2016/004785
Kind Code:
A1
Abstract:
A mutual-inductance contactless current starter for a commercial refrigeration compressor motor. A permanently running capacitor (C2) is connected between a primary winding leading-out end (M) and a secondary winding leading-out end (S) of a motor. A primary and secondary winding combination leading-out end (L) is connected to an end B of an alternating-current power supply. The mutual-inductance contactless current starter comprises a current transformer (L1) and bidirectional controllable silicon (T). One end (1) of a primary coil of the current transformer (L1) and one end (3) of a secondary coil of the current transformer (L1) are jointly connected to an end A of the alternating-current power supply. The other end (2) of the primary coil of the current transformer (L1) and a T1 pole of the bidirectional controllable silicon (T) are jointly connected to the primary winding leading-out end (M) of the motor. The other end (4) of the secondary coil of the current transformer (L1) is connected to a G pole of the bidirectional controllable silicon (T). A T2 pole of the bidirectional controllable silicon (T) is connected to the secondary winding leading-out end (S) of the motor. The mutual-inductance contactless current starter is energy-saving and highly efficient, has a simple circuit structure and high universality, can withstand high current, and improves the starting safety of the motor while ensuring reliable starting.
