6 FAQs about [New capacitor high power motor]

Can a low-inductance high-current film capacitor be used for traction motor drive inverter?

In order to handle high current in a high temperature environment, a low-inductance high-current film capacitor is proposed to replace the conventional electrolytic bulk capacitors for a 75 kW traction motor drive inverter. The proposed design results in significant size reduction and performance improvement over the existing one.

What is a bulk capacitor in a motor driver?

It is common to include large "bulk" capacitors as part of the motor driver design. These bulk capacitors act as a local reservoir of electrical charge to smooth out the motor current variation. Designers look for guidance on the appropriate values of bulk capacitance.

Can a DC-BUS capacitor be used for a 75 kW traction motor drive inverter?

Conventional inverter design sizing DC-bus capacitor based on voltage ripple is no-longer effective. In order to handle high current in a high temperature environment, a low-inductance high-current film capacitor is proposed to replace the conventional electrolytic bulk capacitors for a 75 kW traction motor drive inverter.

Should a motor drive system have more bulk capacitance?

Having more bulk capacitance is generally beneficial, while the disadvantages are increased cost and physical size. This application note discusses general guidelines for selecting the amount of capacitance needed in a motor drive system. All trademarks are the property of their respective owners.

How many capacitors should a DC motor power supply have?

It is often recommended to provide more than one value of capacitor on the motor power supply. The larger value capacitors typically provide the best low-frequency response, while smaller value capacitors provide better high-frequency response. In a real DC motor drive system, bulk capacitors are a common necessity.

Do 48 volt capacitors need to be rated for high power?

In the context of high power, a 48-V system needs ceramic capacitors rated for a minimum of 100 V, or 2 multiplied by 48 V, which equals 96 V with the closest industry rating at 100 V. As a result, 48-V rated capacitors in the power stage are not helpful and must be sized accordingly.
