Frequently Asked Questions
What are the advantages of Mitsubishi IPM over discrete solutions?
Mitsubishi IPM advantages: (1) Integration - IGBTs, diodes, driver, and protection in one package. (2) Simplified design - Reduces design time and component count. (3) Optimized switching - Gate driver optimized for IGBT characteristics. (4) Protection - Built-in OC, OT, UVLO reduce external circuitry. (5) Reliability - Factory-tested and characterized performance. (6) Size - Compact compared to discrete solutions. (7) Cost - Total system cost often lower despite higher module cost. For industrial applications, IPM provides best balance of performance, reliability, and design simplicity.
Choose IPM for industrial applications requiring reliability and quick design turnaround.
How does the IPM protection work?
IPM protection functions for PS21765-PAXC: (1) Overcurrent (OC) - Compares Vce(sat) to threshold; triggers soft turn-off when exceeded. (2) Overtemperature (OT) - Temperature sensor triggers shutdown at 145°C. (3) Undervoltage (UVLO) - Disables outputs if supply voltage drops below 12.5V. (4) Fault output (FO) - Open-drain signal indicates fault to MCU. (5) Soft shutdown - Controlled turn-off limits voltage overshoot. (6) Auto-restart - Returns to normal operation after fault clears. (7) Fault retention - Latches until reset signal received. These protections prevent damage from most fault conditions.
Connect FO pin to MCU interrupt; implement fault handling routine to reset IPM.
What switching frequency is supported by PS21765-PAXC?
PS21765-PAXC switching frequency: (1) Maximum frequency - 20kHz for high-speed operation. (2) Recommended range - 5-15kHz for most applications. (3) Trade-off - Higher frequency increases switching losses. (4) Thermal limits - Check losses at chosen frequency. (5) EMI - Higher frequency increases EMI concerns. (6) Application specific - Servo drives typically use 5-10kHz. (7) PWM resolution - Higher frequency improves current control resolution. The IPM supports space vector PWM and sine wave PWM techniques.
Use 5-10kHz for servo drives; up to 20kHz for high-speed applications.
Can PS21765-PAXC be used for robot joint control?
Yes, PS21765-PAXC is excellent for robot joint control: (1) Current rating - 25A supports joint motors up to 7.5kW. (2) Switching speed - Fast switching enables precise torque control. (3) Protection - Comprehensive protection for industrial environments. (4) Size - Compact package fits robot arm designs. (5) Reliability - High MTBF for continuous operation. (6) Temperature - Wide temperature range for industrial use. (7) Integration - Reduces PCB space in compact robot designs. Recommended for 6-axis robots and SCARA robots requiring precision motion control.
Ideal for robot joints up to 7.5kW; integrate with robot controller for coordinated motion.
How do I implement current sensing with PS21765-PAXC?
Current sensing implementation: (1) Shunt resistor - Place in DC- link for total current measurement. (2) Amplifier - Use differential amplifier with appropriate gain and bandwidth. (3) ADC input - Connect to MCU ADC for digital conversion. (4) Phase currents - Calculate from DC-link current using PWM sector. (5) Overcurrent trip - IPM monitors Vce(sat) for hardware protection. (6) Software protection - Compare measured current to software limit. (7) Filter - Add low-pass filter to reduce switching noise. For servo applications, use dedicated current sensing ICs for best performance.
Use shunt resistor sensing with differential amplifier; implement software overcurrent limit.
What gate drive power supply is needed for PS21765-PAXC?
Gate drive power supply requirements: (1) Supply voltage - +15V ± 10% for gate drive. (2) Current - 20mA per channel typical. (3) Isolation - 2500Vrms isolation required from control side. (4) decoupling - 100nF ceramic capacitors on each supply pin. (5) Ripple - Keep supply ripple below 500mV. (6) Start-up - UVLO disables output until supply stabilizes. (7) UVLO thresholds - On at 12.5V, off at 10.5V. Use isolated DC-DC converter with adequate isolation rating.
Use isolated 15V DC-DC converter with >2500V isolation rating.
