Explore our elite collection of high-frequency rectifiers, modular telecom inverters, and high-efficiency step-down converters tailored for heavy industrial, automotive, and telecommunication networks.
Leveraging Wide Bandgap Semiconductors (GaN & SiC) to Redefine Power Densities, Thermal Constraints, and Conversion Efficiencies.
As micro-grids, high-voltage automotive propulsion, and telecommunication networks scale globally, the requirements for electric power processing units have migrated past raw capacity. The transition from legacy silicon-based topologies to Wide Bandgap (WBG) semiconductors—most notably Silicon Carbide (SiC) and Gallium Nitride (GaN)—remains the single largest inflection point in power electronics. At Guangzhou EVS Powers, our research and development programs address this shift directly, optimizing switching frequencies while minimizing parasitic losses.
To support next-generation industrial rectifiers, such as our 110V/220V modular power systems, EVS utilizes interleaved CCM (Continuous Conduction Mode) Active PFC. This architecture maintains a power factor close to 0.99 under fluctuating loads, heavily suppressing harmonic distortion in compliance with EN61000-3-2. The DC-DC stage features full-bridge LLC resonant converters, enabling Zero Voltage Switching (ZVS) on the primary side and Zero Current Switching (ZCS) on the synchronous rectification side. This approach pushes efficiency limits to 95.8%, mitigating heat generation at the system level.
Decentralized Power Infrastructure Engineered to Support Global Enterprise Domains.
48V and 110V DC bus architectures demand unbroken redundancy. Our N+1 modular rackmount rectifiers and pure sine wave inverters feature active current sharing, allowing hot-swap expansion without system interruption. Advanced telemetry interfaces (RS485, CAN bus, SNMP) provide diagnostic oversight.
Machinery, motor control, and electric vehicles require robust galvanic isolation and high peak power tolerances. EVS high-efficiency DC-DC step-down and step-up boost converters are engineered to survive transient spikes, high vibrational stresses, and severe thermal environments from -25°C to +65°C.
Reliable backup power is crucial for infrastructure protection. EVS dual-input systems and hybrid rectifiers seamlessly bridge grid power and DC battery arrays, guaranteeing continuous 110VDC/220VDC supply lines for circuit breakers, protection relays, and emergency signaling systems.
Guangzhou EVS Powers Co., Ltd. integrates advanced automation with strict quality control to guarantee supply chain resilience and reliable performance.
Located in the international trade hub of Guangzhou, Guangzhou EVS Powers Co., Ltd. is a specialized manufacturer of switching power supplies, DC power systems, power supply units, DC-DC converters, and power inverter series. We view client satisfaction as our primary mission, product quality as our developmental foundation, and cost optimization as our key competitive advantage. Through reliable credit standing and dedicated service, we have built long-term partnerships with clients across Europe, North and South America, Australia, the Middle East, and Southeast Asia.
Our facility runs on a modern Factory 4.0 framework. Each phase of production—from automatic wire winding and component placement to solder profiling and multi-stage testing—is tracked through our MES (Manufacturing Execution System). By monitoring real-time production parameters, we prevent defects early in the cycle, ensuring consistent performance for every batch of OEM/ODM units.
Our systems undergo comprehensive testing protocols to ensure reliability in challenging operating conditions.
To meet high performance expectations, we subject our products to rigorous testing. Each custom or standard batch undergoes isolation resistance, dielectric withstand, environmental thermal cycling, and automated microscopic solder analysis.
Our testing facility uses high-precision diagnostic systems to verify performance metrics like low output ripple, precise voltage regulation, and fast transient response times before shipment.
Providing reliable localized solutions that comply with major safety and electrical standards.
OEM projects require compliance with specific regional standards to allow seamless deployment in diverse markets. EVS designs are pre-tested to meet CE, FCC, RoHS, and local EMC requirements. This simplifies the certification process and speeds up time-to-market for our global partners.
