Why Choose HCPL030 High Current Source?
The trend of high current in practical applications of IGBT/SiC Power semiconductor devices
Power semiconductor devices, used in fields such as power rectification, inverter, and frequency conversion, are equivalent to the "CPU" in the field of power electronics. It has the characteristics of high voltage withstand, high current, and low loss. With the upgrading of technology, the on state power consumption, switching time, and switching power consumption are constantly decreasing.The device's withstand voltage value ranges from hundreds Volt to thousands Volt, and the current range includes tens A to thousands A.
They are widely used in industrial control, household appliances, electric vehicles, new energy photovoltaic and other fields. Common power semiconductors include power diodes, power MOS, IGBT, and third-generation semiconductor devices such as SIC MOS and GaN HEMT.
Test requirement
In testing, some parameters require the use of providing current measure voltage(FIMV) methods, such as Vce testing.
High current output has fast response and no overshoot
Adopting Precise self-developed high-performance pulse high current source.Integration of source and measurement, fast response to output establishment, without overshoot.
In high current testing, high-speed narrow pulse mode is used to reduce the thermal effect of the device.For example,in the testing of Vcesat and Rdson.
