As Vietnam transitions into a globally significant hub for semiconductor processing, smart electric vehicle fabrication, and precision electroplating, the demands placed upon energy stability have scaled exponentially. To drive these processes safely and with unparalleled repeatability, engineering setups require rock-solid AC/DC power converters. Below, we showcase four of our premier, high-capacity products meticulously tailored for integration into local setups across Hanoi, Bac Ninh, Binh Duong, and beyond.
Vietnam has emerged as a premier powerhouse for high-technology hardware assembly, semiconductor encapsulation, and advanced metal chemistry in Southeast Asia. This growth, fueled by robust regional policies and investments from global silicon giants, has transformed areas such as Bac Giang, Da Nang, and Dong Nai into hotbeds for complex assembly lines. These lines operate around the clock, requiring ultra-stable energy configurations that standard power systems simply cannot handle.
The core challenge lies in the nature of modern industrial processes: semiconductor testing ovens, large-scale electroplating vats, and fast EV DC charging piles demand massive quantities of electricity. A 10000W to 12000W (10kW - 12kW) continuous load threshold is the baseline sweet spot for high-power conversion. Any drop in voltage stability or fluctuation in power factor can compromise wafer fabrication runs or result in uneven thicknesses on plated metals. For localized factories operating in Vietnam, employing AC-DC conversion systems equipped with active power factor correction (PFC) and multi-phase utility configurations ensures line safety, prevents excessive thermal strain, and lowers overall electricity overheads.
Globally, the demand for high-power switching power supplies is transitioning from simple linear regulation to software-defined, digital power management systems. Silicon Carbide (SiC) and Gallium Nitride (GaN) materials are replacing traditional silicon switches, pushing system efficiencies beyond 95%. Concurrently, control interfaces are shifting from basic analog dials to remote, network-integrated digital buses (PMBus, Modbus, EtherCAT) that allow operators to control power levels directly from central PLC stations.
In Vietnam, manufacturers face unique environmental and infrastructural challenges. The local tropical climate exhibits high ambient temperatures and humidity levels exceeding 85% for much of the year. In coastal cities like Hai Phong, airborne salt particles add risk for galvanic oxidation. When importing high-power electronics, local factories require special protective layers—such as conformal coatings, moisture barriers, and active cooling configurations—to prevent catastrophic short circuits. Our custom 10000W-12000W power topologies address these problems with durable internal isolation and thermal layouts engineered to handle tropical climates.
Converting three-phase utility lines (typically 380V / 415V AC in Vietnam) down to clean, selectable DC voltages ranging from 24V up to 1000V requires precision architecture. Our power units utilize a Phase-Shifted Full-Bridge (PSFB) topology coupled with Zero Voltage Switching (ZVS) technology. This reduces switching losses, ensuring energy conversion efficiencies remain high at 88% to 89% even when operating under full load conditions.
By implementing active temperature-controlled cooling fans and robust filtering circuitry, we keep harmonic distortions (THD) low, preventing disruption to sensitive analytical equipment nearby. The system's modular control card structure supports customizable output voltages, making it easy to adapt to changing power requirements on the factory floor.
From high-current, low-voltage electroplating (e.g., 24V or 30V for chromium solutions) to high-voltage capacitor testing (up to 1000V), our adjustable configurations match specific process parameters.
Components receive vacuum glue filling and moisture-proof lacquer coatings, ensuring protection against dust, humidity, and high temperatures inside Vietnamese assembly plants.
Our high-power switching power supplies are deployed in several key industrial sectors across Vietnam:
In Binh Duong and Dong Nai’s metalworking zones, our 30V-10000W rectifiers deliver high, stable DC current, ensuring consistent thickness and adhesion in rust-prevention coatings.
As Vietnam’s EV charging network expands, our 12000W adjustable AC-DC units serve as reliable power sources for DC fast-charging development, research, and validation testing.
Electronics manufacturing hubs in Bac Ninh use our high-stability 800V and 1000V DC supplies to stress-test microprocessors and passive components under high temperatures.
Operating out of our 10,000 square meter factory in Shanghai, we export premium power systems worldwide. Our 15-year specialization in high-power regulated systems guides every step of our production process. We maintain a product qualification rate of 99.9% through manual oversight and computer-assisted diagnostic testing. Below is an overview of our manufacturing workflow:
