ON Semiconductor Releases Integrated Solutions for Industrial Motor Drives at APEC 2021

ON Semiconductor (Nasdaq: ON), driving energy efficient innovations, has introduced a new, integrated, converter-inverter-power factor correction (PFC) module for driving motors in applications such as fans and pumps in industrial motor drives, servo drives and heating, ventilation and air conditioning (HVAC).

The new NXH50M65L4C2SG and NXH50M65L4C2ESG are die-cast power integrated modules (TMPIMs) based on a standard aluminum oxide (AI2O3) substrate and an enhanced low thermal resistance substrate, respectively. Ideal for rugged industrial applications with high output power, these modules contain a converter-inverter-PFC circuit consisting of a single-phase converter with four 75 A, 1600 V rectifiers. The three-phase inverter uses six 50 A, 600 V IGBTs with integrated reverse diodes, and the dual-channel interleaved PFC includes two 75 A, 650 V PFC IGBTs with integrated reverse diodes, and two 50 A, 650 V PFC diodes. The die-cast power integrated module embeds a negative temperature coefficient (NTC) thermistor to monitor the device temperature during operation.

Because the module is pre-packaged with an optimized layout and configuration, parasitic elements are very small compared to discrete PCB-based designs, enabling a wide PFC switching frequency range between 18 kHz and 65 kHz. The energy-efficient NXH50M65L4C2SG and NXH50M65L4C2ESG are rated at 50 A and can be used in applications up to 8 kW, and are the latest devices in ON Semiconductor's TMPIM family. Other devices are rated at 20 A and 30 A.

The compact die-cast DIP-26 package measures only 73mm x 47mm x 8mm - saving 20% ​​area over current solutions, enabling higher power density levels. The sealed and robust package includes an integrated heat sink (6mm from the pins) and offers a high level of corrosion resistance.

ON Semiconductor also offers Silicon Carbide (SiC) configuration options to further increase switching frequency and efficiency.

The new NXH50M65L4C2SG and NXH50M65L4C2ESG are paired with the FAN9672 PFC controller and gate driver solutions, including the new NCD5700x family of devices. The recently introduced NCD57252 dual-channel isolated IGBT/MOSFET gate driver provides 5 kV of galvanic isolation and can be configured for dual low-bridge, dual high-bridge or half-bridge operation. The NCD57252 is available in a small SOIC-16 wide-body package and accepts logic-level inputs (3.3 V, 5 V and 15 V). This high-current device (source current 4.0 A/sink current 6.0 A at Miller plateau voltage) is suitable for high-speed operation due to the typical propagation delay of 60 ns.

Driving the motor in the most energy-efficient way is key to simplifying installation, reducing heat buildup, improving reliability, and reducing system costs. ON Semiconductor's TMPIM devices standardize output pins, minimize parasitic elements, and provide designers with a high-performance "plug-and-play" solution. Combining the NXH50M65L4C2SG and NXH50M65L4C2ESG with the FAN9672 and NCD57252 provides a quick design path to achieve precise and energy-efficient motor control solutions.

During APEC 2021, ON Semiconductor will showcase SiC solutions for industrial applications.
