Program overview

The on-board charger is built in the new energy vehicle, which is used to charge the on-board high-voltage battery from the AC grid when parking. The battery used is usually more than 400V, and is developing towards higher voltage and higher number of battery strings. In order to realize a faster and lighter vehicle charging scheme, the new trend of charging power is upgraded from 6.6kw to 11kw. Generally, the current flows from the grid to the battery in one direction, but there are also two-way flow design schemes. Nano chip micro provides complete solutions for isolation voltage, isolation current detection, isolation drive and isolation communication, helping customers achieve higher power density OBC solutions.

Single Phase 10A Voltage Dips Generator

Model：VDT S10

Voltage dips/sags, short interruptions are caused by failures of the power grid and power facilities or sudden large changes in loads. In some cases, there will be two or more consecutive dips or interruptions. Voltage changes are caused by continuous changes in the loads connected to the grid. If the EUT cannot respond in time to changes in the power supply voltage, it may cause malfunctions. Voltage dips generators are used to evaluate the performance of electrical and electronic equipment when subjected to voltage dips/sags, short interruptions, and voltage changes. Products fully meet the requirements of standards IEC/EN 61000-4-11 and GB/T17626.11.

Single phase 5kV burst generator EFT S4

Model：EFT S4

In the circuit, such as from the switching transient process (cutting off inductive loads, bouncing relay contacts, etc.), it will usually interfere with other electrical and electronic equipment in the same circuit. This kind of interference is characterized by high amplitude, short rise time, high repetition rate and low energy. Clusters of narrow pulses can charge the junction capacitance of semiconductor devices, which may cause circuit or equipment errors when accumulated to a certain extent. The burst generator determines a common reproducible evaluation basis for evaluating the performance of power supply ports, signal, control and grounding ports of electrical and electronic equipment when disturbed by electrical fast transient bursts. The products meet the requirements of new standards such as iec61000-4-4, en60100-4-4 and gb/t17626.4.
