Ripple Voltage
Ripple Voltage is the difference in voltage between “peak” and “valley” from our DC power supply.
...
The maximum ripple voltage that we have within our controller is 10% of the nominal voltage.
When the motor pulls current, it causes the DC Bus Voltage to drop.
Large amounts of current flowing back into the power supply can cause voltage spikes at the output terminals of the motor systems as well as on the power supply. The excess current can be produced by the motor acting as a generator or by the stored energy on the motor flowing back to the supply during fast decay. This occurs because the kinetic energy that the motor possesses when it is spinning has to dissipate - which occurs by energy being transferred back into the circuit. This voltage that is output will cause noise to the input. The goal is to minimize the voltage spikes by controlling and absorbing all of the excess energy.
