As industrial automation continues to advance, industrial robots and collaborative robots (cobots) demand servo drive systems that are smaller, more precise, highly reliable, and resistant to electromagnetic interference. At the heart of every servo drive is the power module, which directly impacts positioning accuracy, motion stability, and system lifetime.
SHYSEMI has developed a dedicated 600V Intelligent Power Module (IPM) specifically for industrial robotic arm servo drives. Optimized for robot joint applications, this solution is ideal for both compact and heavy-duty industrial robots, making it an excellent domestic alternative to imported power modules.
Built on a highly integrated 7-in-1 architecture, the SHYSEMI IPM replaces traditional discrete component designs that require complex wiring, occupy more PCB space, and increase system failure rates. The module integrates a PFC stage, three-phase inverter, high-voltage gate driver IC, protection circuits, and temperature sensing, providing a complete power solution for 100 W to 3.5 kW servo motor drives.
It is widely used in six-axis industrial robots, collaborative robots, pick-and-place systems, palletizing robots, and other industrial automation equipment.
Key Architecture Advantages for Demanding Robot Applications
Industrial robotic arms frequently operate under rapid start-stop cycles, continuous acceleration and deceleration, long operating hours, and electrically noisy factory environments. SHYSEMI has optimized its IPM architecture to meet these demanding conditions.
1. Highly Integrated Design for Compact Servo Drives
The module integrates a proprietary 7-channel high-voltage gate driver IC, fast recovery diodes (FRD/MUR) , bootstrap diodes, and the complete power stage into a single package.
By eliminating many external driver, rectifier, and bootstrap components, the design can reduce servo drive PCB area by more than 35%, making it easier to develop compact and lightweight robot joints while simplifying circuit layout and improving overall reliability.
2. Excellent Thermal Performance with IMS Technology
All models use an industrial-grade Insulated Metal Substrate (IMS) combined with high-temperature molding materials.
With insulation capability up to 6000 Vrms and excellent heat dissipation, the module quickly transfers heat away from the power devices, preventing thermal accumulation and power derating during continuous operation. It maintains stable performance even in ambient temperatures up to 180°C, making it ideal for high-load industrial environments.
3. Flexible Control Interface
The module supports both 3.3 V and 5 V logic-level inputs, allowing direct connection to common DSP and MCU controllers used in industrial robots.
No additional level-shifting circuitry is required, reducing hardware complexity and shortening product development cycles.
Five Performance Advantages for Precise and Reliable Motion Control
Industrial robots require fast dynamic response, precise positioning, and comprehensive protection. SHYSEMI's IPM has been optimized to address common issues such as vibration, missed steps, motor stall damage, and unexpected downtime.
1. Fast Switching for High-Precision Motion
Optimized IGBT switching performance supports PWM frequencies up to 20 kHz, delivering rapid motor response with minimal delay.
This enables accurate control during high-speed positioning, precision gripping, repeated acceleration and deceleration, and low-speed fine motion, helping maintain excellent repeat positioning accuracy for applications such as electronics manufacturing, lithium battery production, and precision metal processing.
2. Comprehensive Five-Level Protection
The module integrates multiple protection functions, including:
- Overcurrent protection
- Short-circuit protection
- Undervoltage lockout (UVLO)
- Overtemperature protection
- Hardware interlock protection
When abnormal conditions such as motor stall, overload, or unstable power supply occur, the integrated FLT fault output immediately reports the fault while the power stage is shut down within microseconds. This effectively protects both the motor and drive system while minimizing production downtime.
3. Real-Time Temperature Monitoring
An integrated high-accuracy NTC thermistor continuously monitors substrate temperature and provides analog temperature feedback.
The controller can automatically reduce output power based on thermal conditions, preventing overheating during continuous heavy-load operation and ensuring reliable performance across varying ambient temperatures.
4. Excellent EMC Performance
The gate driver layout is carefully optimized to minimize gate loop length and reduce output impedance.
This significantly improves electromagnetic compatibility (EMC), allowing stable operation in industrial environments filled with variable frequency drives, contactors, and electrical noise while reducing vibration, signal interference, and control instability.
5. Cost-Effective Replacement for Imported IPMs
Electrical specifications, package dimensions, and pin configurations are fully compatible with leading international brands.
The modules support direct drop-in replacement without modifying existing PCB layouts or control software. Combined with stable production capacity and reliable lead times, manufacturers can reduce overall BOM costs by 15%–22% while accelerating localization of robotic equipment.
