Variable frequency drive with separately adjustable voltage and frequency

The inverter with separately adjustable voltage and frequency can be applied to motor testing systems, variable frequency power supplies, and other applications where voltage and frequency need to be adjusted separately.
This inverter solves the problem that ordinary inverters can only operate at a fixed voltage-frequency ratio (constant V/F curve), expanding the application of inverters from ordinary uses to special demand applications. The applicability of the inverter is broader.
It can be applied to motor testing systems, suitable for testing different types of motors, and can be used for locked rotor tests of motors.
When used for variable frequency power supplies, it can achieve fixed frequency, with voltage adjusted according to load requirements, or form a voltage closed-loop control to stabilize the output voltage.
Voltage and frequency can be adjusted separately, with a maximum output frequency of 500Hz, input voltage of AC or DC, output voltage of 0-690V, and maximum power of 5000KW.
