IT6500 series two-quadrant power supply is not simply a combination of a power supply and electronic load, but it is a continuous source and load. For traditional two-quadrant power supply, there will be a short jump and discontinuity across positive and negative currents. As a high-speed two-quadrant power supply, IT6500C (1800W-30KW) series has Loop-Mode function so as to realize high-speed current transition between power supply mode and electronic load mode, to achieve fast switching between sourcing and sinking current,even can achieve seamless switching under certain conditions, thus avoiding overshoot of voltage or current. That enables it to be widely used in energy storage device testing, such as batteries, battery encapsulation and battery protection panel etc.

IT6500C series can be used as both a power supply and an electronic load. It greatly enlarges the current sinking range of the power supplies. It enables sinking of current and power, thus it can be applied to applications requiring fast current sink test and batteries charging/discharging test. Each IT-E500 series power dissipater unit provides up to 3kW power sinking capability for the IT6500C series power supply. To meet higher power discharging test demand, multiple power dissipater units can be paralleled. The IT-E500 series power dissipater unit can extend the current sinking capability to 100%, 200%, 300% of the source range and the power sinking capability up to 300% of the Power sourcing capability. (Max. Power sink is 90kW). Meeting demanding requirements of high power discharging test.

To conquer the demanding testing requirements existing for a long time in various applications, ITECH developed an innovative industry-leading CV & CC priority concept. The IT6500 is available for high-speed test applications with-out overshoot. Users can choose the desired output mode. Voltage high-speed mode or current no overshoot mode by choosing the loop response speed and loop operation mode. It is suitable for high-power integrated circuit test, charging / discharging test, military, solar array simulation and the transient simulation / characteristic of automotive electronics.

For practical electric vehicle (EV) battery test, the ultra-realistic simulation of regenerative braking current is necessary, the whole test should be finished within 10ms. So the simulation result depends on the response speed of the relating testing device.

1. Traditional solution: Adopt two single units, such as DC Power Supply + Electronic Load, which is of complex configuration, low efficiency and thus can’t meet the testing requirements.

2. ITECH solution: IT6500C provides fast and seamless switching across current outputting and sinking, combined with IT-E500 power dissipater units, IT6500C can meet the testing requirements easily. It is an ideal solution for EV braking current’s regenerative battery test.
