6 FAQs about [Inverter withstand voltage power]

What is withstand voltage?

A very high voltage (up to the range at which dielectric breakdown is likely to occur) is applied to determine the withstand voltage. The voltage is gradually increased and the point at which dielectric breakdown occurs is called the withstand voltage (limit voltage). The Purpose of Withstand Voltage Tests

What is withstand voltage test?

In withstand voltage test, a high AC (or DC) voltage is applied to a test object. The leakage current that flows when the object breaks down is detected in order to determine whether the test was passed or failed. In other words, dielectric breakdown equals an increase in electric current.

What is a full scale inverter test?

The full scale that can be measure is 1026 V. The measurement is done by applying a DC-Link voltage between 50 V to 1000 V. During this test, the inverter is running and the motor is disconnected, which brings a switching frequency of 16 kHz. The uncalibrated error is observed to be ±1% throughout the measurement range.

What is a 3 phase inverter?

The three-phase inverter is designed to operate from the DC bus voltage up to 1200 V. This design uses an IGBT module instead of discrete IGBTs. This reference design is intended to support various makes of IGBT modules so a commonly used footprint of IGBT module is selected.

How does a DC inverter work?

The inverter is designed to protect against overload, short circuit, ground fault, DC bus undervoltage and overvoltage, and IGBT module over-temperature. The DC bus voltage is dropped down using the resistor divider and fed to one more AMC1311 for sensing. The under- and overvoltage are programmed in the MCU using the sensed signal.

What is a high-end three-phase inverter?

There are many end applications such as HVAC, solar pumps, and appliances where cost is major concern without compromising the performance. High-end three-phase inverters use ΣΔ modulators for current sensing, which also asks for using expensive controllers with built-in SINC filters.
