Exhibition Highlights | Micsig Wraps Up a Successful Appearance at PCIM Asia Shenzhen 2026

From August 26 to 28, 2026, PCIM Asia Shenzhen 2026 was held at the Shenzhen World Exhibition & Convention Center (Bao'an New Venue). This year's exhibition brought together 271 power electronics companies from China and abroad, spotlighting key trends such as AI data center power, transportation electrification, and renewable energy. Micsig presented its full lineup of test and measurement products, including oscilloscopes, optical isolation probes, and current probes, and engaged in in-depth exchanges with attending engineers on measurement accuracy, instrument user experience, and testing needs.

01 Booth Spotlight: The Third-Generation MOIP Optical Isolation Probes

SiC/GaN devices switch fast, operate on high bus voltages, and generate strong common-mode interference, making it difficult for conventional high-voltage differential probes to balance accuracy and safety. The third-generation MOIP series optical isolation probes, built on Micsig's in-house SigOFIT™ optical isolation technology, are the production-ready answer to this challenge:

· Isolation and bandwidth in one: common-mode voltage up to 85 kVpk and bandwidth coverage from 200 MHz to 1.2 GHz;

· Ultra-high common-mode rejection: CMRR up to 180 dB at DC and still 108 dB at 1 GHz; noise floor below 0.3 mVrms; DC gain accuracy better than 1%;

· Measure without calibration: the proprietary ADHOMT analog-digital hybrid laser modulation technology ensures zero temperature drift, eliminates manual calibration, and is ready to measure at power-on, supporting uninterrupted 365-day, 24/7 testing;

· Measurement ranges from ±0.01 V to ±20 kV (customization available), input capacitance as low as 1 pF, and a standard BNC interface compatible with oscilloscopes from all brands.

02 Beyond Probes: Covering the Entire Power Device Test Chain

· Voltage measurement: MOIP optical isolation probes excel in challenging scenarios such as floating half-bridges, high-voltage buses, and switching nodes, pairing with high-voltage differential probes to cover both high and low voltages;

· Current measurement: RCP series Rogowski coils are free from magnetic saturation and handle short-circuit and surge currents, while CP series clamp-on AC/DC current probes cover ranges from milliamps to hundreds of amps, with multiple models including the CP3008 and CP1003B demonstrated on site;

· Waveform analysis: MHO6 series high-resolution oscilloscopes deliver 12-bit resolution, 1 GHz bandwidth, 6 GSa/s sampling rate, 1800 Mpts memory, and 8 channels to support precise measurements such as double-pulse tests and switching loss analysis, with multi-channel models including the MHO3 and MO34 on display as well.

03 On-Site Exchanges

During the three-day show, engineers from the electric vehicle, energy storage, and industrial power supply industries held in-depth discussions with Micsig's technical staff on topics such as common-mode rejection in SiC/GaN double-pulse testing, floating measurements on 800 V platforms, and magnetic saturation under large short-circuit currents, and the live demonstrations attracted wide attention.

Conclusion

Our thanks go to everyone who visited the Micsig booth. Micsig will continue to apply proprietary core technologies such as SigOFIT™ to support the high-quality development of the third-generation semiconductor and power electronics industries.
