The new MTE DC link chokes are designed to reduce DC ripple as well as AC input harmonics. In addition the MTE DC link chokes reduce di/dt slew rates and thus diminish significantly stress placed on the insulation of other connected apparatus.
Unlike input line chokes, DC link chokes do not reduce the input voltage at the fundamental frequency and therefore do not reduce power to variable speed drives, etc.
The DC link chokes are rated for 1000 volts DC and are designed to mitigate harmonics including the fifth order, thus removing to a large extent oscillating torque conditions on direct-connected induction motors.
The new MTE DC link chokes are ideal for PWM inverters and electric vehicle inverters.
