Parasitic motor
WebA parasitic load that steadily discharges the battery. Depending on the size of the load, it may take hours or days until the battery becomes too discharged to crank the starter and start the engine. Perhaps you remember the crude method we used to use to track down parasitic battery loads. WebFeb 12, 2016 · A VFD may report a low-volts fault when the drive dc link voltage drops below 62% of the nominal level for the high setting (480 V ac) and 50% of nominal for the low setting (400 V ac). This can be stated as: 480 V ac x 0.62 x √2 = 421 V dc. The nominal dc link voltage is: 480 V ac x √2 = 679 V dc. The +10% and -15% voltage tolerance in ...

At low frequencies parasitic capacitance can usually be ignored, but in high frequency circuits it can be a major problem. In amplifier circuits with extended frequency response, parasitic capacitance between the output and the input can act as a feedback path, causing the circuit to oscillate at high frequency. These unwanted oscillations are called parasitic oscillations.

This effect is noticeable in single supply gate drivers (0 to +15V). Due to this gate-collector coupling, a high dV/dt transient created during IGBT turn-off can induce a parasitic turn-on effect that is potentially dangerous.
