Explore our elite range of regulated variables, DC-DC bench sources, and system instrumentation engineered for absolute power stability.
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.
As modern semiconductor and EV topologies grow more demanding, basic power outputs no longer suffice. Standard operations require nanosecond dynamic responses, digitally controlled loops, and extreme galvanic isolation to prevent noise interference. MYAMI's design methodology targets low-noise switching and linear execution layouts to assure clean operation during critical testing sequences.
Our state-of-the-art engineering center utilizes leading-edge physical simulation and CAD design structures to produce robust hardware.
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. Today, MYAMI serves research institutions, automotive OEMs, aerospace contractors, and electronics manufacturers across North America, Europe, East Asia, and the Middle East.
Our assembly mapping is calibrated at every interval to ensure consistent output quality, low drift coefficients, and prolonged operational lifespans.

Understanding the transition from traditional silicon topologies to Wide Bandgap (WBG) semiconductors in high-frequency power electronics.
Implementing SiC MOSFET switch gears reduces reverse recovery charge losses by up to 85%. This allows high-voltage DC test sources to run at lower temperatures while increasing power density by 40% compared to traditional Si-based switches.
For highly variable bench supplies, GaN technology enables switching frequencies to exceed 500 kHz. This reduces the size of magnetics (transformers and chokes), providing a compact footprint with under 0.05% load regulation drift.
Our future roadmap targets real-time active power factor correction (PFC) systems capable of achieving a Power Factor (PF) of >0.99 and reducing Total Harmonic Distortion (THD) below 3%, meeting the strict EN61000-3-2 standards.
Providing reliable power solutions across demanding high-precision environments, from sub-microamp laboratory research to multi-kilowatt industrial systems.
Avionics and defense components require highly stable DC sources that can simulate aircraft battery transients (e.g., MIL-STD-704F standards). MYAMI's programmable linear and low-ripple switching power systems simulate sudden engine cranks, voltage drops, and spike conditions. This ensures safety during laboratory verification and validation phases.
Electric vehicle testing requires regenerative loads and high-power DC outputs capable of matching modern lithium battery pack voltages. Our high-voltage supplies are integrated with CAN bus systems, enabling real-time telemetry control to test BMS protection thresholds, thermal runaways, and over-voltage limits under strict conditions.
Corrosive plating operations require continuous current delivery at low voltages (e.g., 12V 1000A) with minimal ripple. Higher ripple values can cause structural defects in plated layers. MYAMI's high-power industrial rectifiers use a multi-phase buck topology to limit ripple output below 1% RMS, ensuring high metal deposition quality.
Testing off-grid and grid-tied inverters requires simulating a solar panel's IV curve under changing environmental conditions. MYAMI's solar simulator firmware allows users to program dynamic temperature and irradiance variables, checking tracking efficiencies to improve system-level performance.
Providing reliable power solutions globally through international safety certifications and technical field support.
Each unit undergoes electromagnetic compatibility (EMC) and low-voltage directive (LVD) tests, ensuring compliance with local grid codes and safety regulations in both Europe and North America.
Designed for industrial grids worldwide, our systems handle standard 110V/220V single-phase lines as well as 380V/480V three-phase systems, with active input filter stages built in.
We provide remote calibration assistance, firmware updates, and local support networks to resolve integration queries quickly and minimize downtime.

Detailed technical answers to help electrical engineers select and configure DC power supplies.
Linear DC power supplies offer clean output with low noise and ripple (often < 1 mV RMS), making them ideal for sensitive RF circuits and laboratory R&D. However, they are heavier and run less efficiently. Switching DC power supplies are more efficient, lighter, and support higher power levels. They use high-frequency switching circuits, which can introduce slightly more electrical noise, but are suitable for bulk power distribution, motor testing, and aging systems.
Transient recovery time is the time it takes for a power supply's output voltage to return to its set level after a sudden change in load current. In automotive testing, where loads change rapidly, a slow transient recovery time (> 100µs) can cause voltage dips or spikes. This can trigger false under-voltage or over-voltage protections in the device under test (DUT). MYAMI supplies feature dynamic compensation loops that keep recovery times below 50µs.
MYAMI programmable power supplies support standard communications interfaces like RS232, RS485, and CAN bus. They use Modbus or SCPI (Standard Commands for Programmable Instruments) command protocols. This allows PLC controllers and central computers to set voltages, monitor currents, and read telemetry data in real time, supporting automated factory workflows.
Our systems include multi-layer protections: Over Voltage Protection (OVP) and Over Current Protection (OCP) shut down the output instantly if configured limits are exceeded. Over Temperature Protection (OTP) monitors the heatsink temperature, and short-circuit protection prevents hardware damage from direct output shorts.
When charging batteries or simulating dynamic battery behaviors, wire resistances and internal cell resistance can cause voltage drops along the supply lines. MYAMI's remote sensing capability measures voltage directly at the battery terminal rather than the supply output terminals, compensating for losses in the cabling to ensure accurate voltage delivery.
