Description

Technical Field

[0001] This utility model relates to the technical field of switched reluctance motor drive devices, specifically a safe charging type switched reluctance motor drive device for golf carts. Background Technology

[0002] Switched reluctance motors (SRMs) are a type of speed-regulating motor developed after DC motors and brushless DC motors (BLDCs). A patent (CN201282441Y) discloses a SRM drive device, belonging to the field of motor drives. The device includes a control circuit, a drive circuit, and a power circuit. For SRMs with a dual-transistor series-connected power circuit, this invention adds timing control functions for the power switches, a midpoint voltage offset processing function, and a short-circuit fault handling function to the control circuit of the existing drive device. This invention can determine whether there is a voltage midpoint offset by detecting the voltage midpoint offset of the filter capacitor and process it accordingly. This invention can also handle short-circuit faults by receiving a short-circuit protection signal from the drive circuit and shutting down the faulty phase output or all outputs according to a certain shutdown sequence. This drive device can protect the motor and operate in a safe state, and is low in cost and easy to widely adopt.

If the wiring harness connection becomes abnormal and cannot be disconnected from the motor in time, the motor may burn out due to the continuous connection of the wiring harness. Therefore, we propose a safe rechargeable golf cart switched reluctance motor drive device to solve the above-mentioned problems. Utility Model Content
