Explore our high-performance programmable AC/DC sources, laboratory-grade variable power supplies, and specialized validation equipment.
Headquartered in Shenzhen, China, Shenzhen Myami Power Technology Co., Ltd. (MYAMI) is a technology-driven manufacturer and solution provider specializing in high-precision, industrial-grade power supplies and electrical test equipment. Designed for engineering rigor, MYAMI bridges the gap between complex electronic research, high-voltage component testing, and scalable industrial automation.
We do not simply manufacture equipment; we design the foundational systems that allow power conversion technologies to operate safely, efficiently, and with traceably high repeatability. Our specialized engineering portfolio focuses on four core operational pillars:
Every MYAMI system is engineered with strict multi-layer protection protocols (OVP, OCP, OTP, and short-circuit safeguards) and complies with international safety and quality standards, including CE, RoHS, and ISO9001. Integrated with standard industrial control protocols (RS485, RS232, and CAN communication), our equipment seamlessly connects to automated production lines and central PC control systems.
Operating from the heart of the world’s most advanced electronics hardware ecosystem enables MYAMI to deliver world-class conversion solutions.
By leveraging Shenzhen's unparalleled semiconductor, transformer magnetics, and passive component cluster, we source components with minimal lead times and ensure strict quality tracking from raw materials to final packaging.
Every single AC/DC converter and programmable source undergoes high-potential (Hi-pot) isolation checks, transient response analysis, and a comprehensive 4-hour dynamic thermal load burn-in phase before shipment.
Our R&D laboratory specializes in modifying loop compensation networks, programming customized firmware protocols (including CAN bus limits and Modbus maps), and adjusting physical form factors for custom chassis configurations.
"In industrial power conversion, stability is measured in millivolts and microseconds. Our engineers design circuits with a high safety coefficient to withstand thermal shock, mains grid fluctuations, and heavy inductive load kickbacks." — MYAMI Engineering Director
The traditional silicon-based switching topology is rapidly approaching its theoretical limits for power density and thermal conductivity. At MYAMI, our design pipeline incorporates Silicon Carbide (SiC) and Gallium Nitride (GaN) switching components. These wide-bandgap (WBG) semiconductors offer lower drain-source on-resistance (RDS(on)), allowing our converters to switch at higher frequencies (up to several hundred kHz) with drastically reduced switching losses. This innovation yields more compact physical packaging, higher power density, and thermal dissipation margins that allow sustained operation at full load without degradation.
Connecting high-power switching power supplies directly to the AC mains can introduce significant harmonic distortion, leading to transmission inefficiencies and potential interference with adjacent electronics. Our AC/DC converters are engineered with advanced Active Power Factor Correction (PFC) circuitry. By continuously monitoring the input voltage waveform, our controllers adjust the input current draw to track the voltage phase, bringing the power factor up to 0.99 under standard operational loads. This minimizes Total Harmonic Distortion (THD) and complies fully with stringent electromagnetic compatibility (EMC) regulations, protecting both the host facility's electrical distribution and local instrumentation.
For applications where clean signal integrity is paramount, such as audio frequency calibration and high-resolution sensor testing, MYAMI offers linear regulated power supplies (e.g., our MY-L6005F series). Linear architecture completely avoids high-frequency switching noise, maintaining output ripple down to sub-millivolt ranges. For applications requiring massive current throughput, variable load testing, or compact bench footprints, our programmable switch-mode power supplies provide unmatched efficiency and rapid dynamic response times to sudden load transients.
From testing the future of mobility to regulating high-precision laboratory processes, MYAMI provides high-reliability power systems.
As the electric mobility market scales, battery pack simulation and On-Board Charger (OBC) testing demand highly stable variable power. MYAMI's adjustable frequency laboratory AC sources and high-power programmable DC units enable developers to simulate real-world battery discharge profiles, input voltage drops, and rapid grid transients. The integrated CAN communication interface ensures direct loop communication with automotive BMS setups.
Testing MPPT algorithms in solar inverters require precise power sourcing. Our variable DC supplies and MPPT charge controllers recreate dynamic solar irradiance profiles. Additionally, our variable frequency AC sources let engineers evaluate how grid-tied inverters perform under differing utility standards (e.g., shifting frequencies from 45Hz to 400Hz and tracking reactive load interactions).
To assure long-term chip reliability, semiconductors must undergo thermal-stress aging. Our programmable DC sources provide continuous, regulated voltage with OVP (Over-Voltage Protection) and OCP (Over-Current Protection). This guarantees that even during a component failure on the burn-in board, adjacent devices are shielded from voltage spikes or cascading shorts.
Scientific validation demands high transparency and repeatability. Our dual-channel teaching oscilloscopes, digital meters, and programmable variable frequency power sources provide students, researchers, and QC technicians with simple, accurate interfaces and physical controls (like high-sensitivity encoders and touch screens) to log measurements with absolute certainty.
We control quality at every workstation. From layout routing and automatic soldering to multi-instrument diagnostic calibration, here is how we build reliability into every unit.
