I. Isolated DC-DC Converter Modules: Safe and Efficient DC Power Conversion
The core function of isolated DC-DC converter modules is to convert one DC voltage into another or multiple DC voltages, whilst achieving safe separation of the input and output circuits through electrical isolation to prevent the transmission of interference.
Key Technical Features
High isolation voltage: The modules generally offer isolation voltages ranging from 2.5 kVrms to 5 kVrms, with some industrial-grade products reaching 10 kVrms, meeting the stringent safety isolation requirements of sectors such as healthcare and industrial control.
Wide input voltage range: Supports wide-range inputs such as 9 V to 75 V, accommodating the power supply requirements of various devices and reducing the complexity of power supply selection.
High Efficiency and Low Power Consumption: Conversion efficiency can reach over 95%, whilst quiescent current is as low as tens of microamperes, thereby reducing the overall energy consumption of the equipment.
Compact Packaging Design: Utilises miniaturised packaging such as SIP (Single In-Line Package) and DIP (Dual In-Line Package), with dimensions as small as 3.8 mm × 7.6 mm, saving space on the PCB.
Typical Applications
Industrial automation: Provides isolated power supplies for PLCs (Programmable Logic Controllers), sensors and servo drives.
Medical equipment: Used in patient monitors, ultrasound equipment and similar devices to prevent the risk of electric shock and ensure the safety of patients and operators.
Telecommunications equipment: Provides stable, isolated power supplies for base station RF modules and optical modules, reducing signal interference.
II. Isolated Gate Driver Power Supply Modules: Enabling Precise Control of Power Devices
Isolated gate driver power supply modules are specifically designed for power semiconductor devices such as IGBTs (Insulated Gate Bipolar Transistors), SiC (Silicon Carbide) and GaN (Gallium Nitride), providing isolated drive voltages to ensure reliable conduction and turn-off of power devices.
Key Technical Features
High-frequency response: Supports switching frequencies of up to 1 MHz, compatible with high-frequency power devices such as SiC and GaN, thereby reducing switching losses.
Precise voltage output: Output voltage is stabilised at 15 V–20 V (forward drive) and –5 V (reverse turn-off), ensuring power devices are fully turned on and completely turned off.
Strong Interference Immunity: Built-in EMC (electromagnetic compatibility) filtering design provides protection against high-frequency noise in industrial environments, preventing erroneous triggering of drive signals.
Over-Temperature and Over-Current Protection: Integrated over-temperature protection (OTP) and over-current protection (OCP) functions automatically cut off the output when the module temperature is too high or the output current is abnormal, thereby protecting the power devices.
Typical Applications
New Energy Vehicles: Provides drive power for IGBT/SiC devices in on-board inverters and DC-DC converters.
Industrial Frequency Converters: Used for power devices in motor drive inverters to enhance the operational stability of the inverters.
Energy Storage Systems: Compatible with power semiconductors in power conversion systems (PCS) to ensure the charging and discharging efficiency of energy storage systems.
III. AC-DC Converters: An Efficient Bridge from AC to DC
AC-DC converters directly convert mains power (AC 100V–240V) into a stable DC voltage, providing a basic power supply for downstream equipment. They are widely used in consumer electronics, industrial equipment and other fields.
Key Technical Features
Wide Mains Voltage Adaptability: Supports a full input range of AC 85V–265V, compatible with mains standards across different regions worldwide, requiring no additional adapters.
High Power Density: Through synchronous rectification technology and a compact thermal design, power density can reach over 2W/cm³, with the module volume reduced by 30% compared to traditional products.
Low harmonic distortion: Features a built-in PFC (Power Factor Correction) circuit, achieving a power factor (PF) of up to 0.99 and total harmonic distortion (THD) below 5 per cent, in compliance with international standards such as IEC 61000-3-2.
Multiple safety certifications: Has obtained global safety certifications including UL, CE and TÜV, meeting the safety requirements of various sectors such as consumer electronics, medical devices and industry.
Typical Applications
Consumer Electronics: Provides DC power for routers, smart home devices and laptop adaptors.
Industrial Control: Used as the power supply for industrial sensors, small PLCs and human-machine interfaces (HMIs).
Medical Devices: Provides a safe and stable DC power supply for portable medical instruments (such as blood glucose monitors and pulse oximeters).
