Delivering Cost-Effective, Low-Power for ePTOs with Air-Cooled Inverter Technology

The manufacturer of electric power take-off (ePTO) needed an air-cooled, high-voltage (HV) inverter that was cost-effective and delivered efficient performance at low power for their air-cooled, 10-kilowatt (kw) ePTO to complement their 75-kw water cooled electric ePTO. The inverter needed to be paired with their chosen motor.

Challenge

Few products on the market exist that can fill that requirement. Many are either overpowered, too expensive, or water-cooled. The ePTO manufacturer turned to a provider that is an expert in electric and hybrid systems.

Solution

The solution was a high-voltage, low-power, air-cooled inverter, which can operate at high voltage up to 800 volts (V) and deliver 10 kW of continuous power. This inverter allowed the ePTO to support the operation of a wide range of ancillary systems that require peak current up to 24 amps.

The system’s success centers around an advanced, air-cooled HV inverter designed for efficient performance at lower power outputs. The inverter can operate at voltages up to 800 V and reliably deliver continuous power at the 10-kW level, enabling the support of ancillary systems that require high peak current. Its air-cooled design eliminated the need for water-cooling infrastructure, resulting in a cost-effective and practical solution for engineers and designers seeking compact, efficient power electronics.

Impact

The manufacturer was able to create a prototype ePTO, without the requirement of water-cooling circuits, delivering low power at high efficiency for testing and show displays.

Other HV Inverter Applications

Typical applications for this type of inverter include:

• ePTO systems for industrial and utility vehicles

• Electric auxiliary drives for commercial and specialty vehicles

• Integration into electric and hybrid platforms where space, cooling simplicity, and cost are concerns

• Support of ancillary equipment such as pumps, compressors, and fans requiring variable speed and efficient power delivery in high-voltage architectures
