Technical FAQs 4

What is a high voltage resistor?

for High Voltage ApplicationsTT Electronics offers one of the most diverse ranges of high voltage resistors. the HV range from 1 to 100kV products are available which provide safety discharge, reliability in balancin and accuracy in measurement. For designers requiring a resistor with parameters outside of this range, bespoke solutions specific

How does a high-voltage full bridge inverter work?

A high-voltage full bridge inverter works by converting the DC voltage V1 to a high-frequency square wave AC voltage. This AC voltage is then supplied to a 20kHz frequency high-voltage transformer T1, which, after the boost rectifier, provides power to the load. The inverter high-voltage full bridge drives the routing components and the IGBT power modules.

What is the main circuit of an inverter?

The main circuit of an inverter includes an inverter DC power supply, IGBT bridge inverter, protection circuits, high frequency high voltage transformers, and high frequency high voltage silicon stack (Rectifier).

What is a DC-link capacitor in a traction inverter?

Figure 1. Simplified Block Diagram of a Traction Inverter The DC-Link capacitor is a part of every traction inverter and is positioned in parallel with the high-voltage battery and the power stage (see Figure 1). The DC-Link capacitor has several functions, such as to help smooth voltage ripples, filtering unwanted harmonics and reducing noise.
