From rectifier, DC bus and IGBT / IPM / SiC inverter stage through to gate drive, current sensing and DSP control — kitted stage by stage across the full 0.4 kW to 630 kW range, so one BOM is filled in one place.
20 years in industrial automation, building tailored PLC, VFD, servo drive and robotics control solutions that help manufacturers cut cost and compete.
Capacitors, resistors, inductors, diodes, transistors, thyristors, MOSFETs, bridge rectifiers, Zener diodes, TVS, MCUs, DSPs and IPMs — all compliant with RoHS and REACH.
Working closely with Jingyoujia, Jufeng, Cuizhan and Anxinwei — IGBT, SiC, IPM, gate driver ICs and frequency devices come straight from factory channels, with stable supply and full traceability.
Built around motor drive solutions — complete control systems above, fully kitted components below.
Kitted stage by stage — rectifier, bus, inverter, gate drive, current sensing and control — across the full 0.4 kW to 630 kW range.

ProductsThe hard part of a drive is never one device — it is matching the whole chain. We kit that chain in one go.
We understand the circuit and we control the sourcing and lead time — standardised and customised service combined.
Deep in industrial automation control since 2006.
Standardised and customised service combined, flexible across customer sizes.
Products meet RoHS certification and REACH requirements.
Backed by a strong engineering team, with technology serving the market.
IGBT, SiC, IPM and gate drivers cover the core of the drive power path, and every partner fab holds international certification.
Specialist frequency device manufacturer with 14 years of experience, covering SMD and through-hole crystals
Power semiconductor specialist and the only company in China developing a full in-house range of gate driver ICs and IGBTs
Power device manufacturer with integrated capability from chip design through to module production
Semiconductor technology company and authorised distributor for the ISOMICRON brand in Greater China
Supply brands are stocked sourcing and spot supply — Qinjin is not an authorised distributor for them.
Open any industry to see the design constraints that actually matter there, and the parts we can supply against them.
Whether you need a drive BOM filled or a system built from the topology up, our engineers can take it on. We reply within one hour during business hours.
