Device overview:
      The bidirectional DC test power supply is specially developed for the motor controller, drive motor and vehicle test of the new energy electric vehicle industry. Using PWM four quadrant rectifier, bidirectional BUCK converter, numeric control and other core technology development, has the bidirectional flow of energy, 100% energy feedback, high precision, fast transient response, high conversion efficiency, low pollution to the grid, the communication interface is rich, powerful protection and other major features.
       It is suitable for the early stage development, the latter type test, the reliability test and the product line test of the electric motor and its controller, the electric automobile powertrain system and other fields.
       Meet the national standard "motor drive system _ first part: GB/T18488.1-2015- electric vehicle technical conditions"; "driving motor system _ second part GB/T18488.2-2015-: Test methods for electric vehicles"; "GB/T29307-2012" test method of electric vehicle driving motor system reliability test project using the power requirements.

Principle introduction:


      The core circuit of bidirectional DC power supply feedback test machine is composed of two parts: PWM bidirectional rectifier circuit and DC/DC, can provide the DC power supply is stable and adjustable for motor and controller in the types, performance and durability test, can also be speeding experiment in motor back EMF energy feedback power grid.
