The PFB LITE peak spike suppressor uses carefully selected TVS diodes to absorb dangerous voltage peaks to protect the connected components. Peak spike suppressors are designed for use with electrolytic capacitors. The capacitor can be mounted directly on it. It prevents the voltage from rising from a certain voltage by absorbing and absorbing the energy of the voltage spike. For electric drive systems that use brushless motors and lithium polymer batteries, very high voltage and current peaks will appear. The most widely known way to keep them in an area where they will not harm other connected loads is to use capacitors. This is actually a very good method. The capacitor suppresses all fluctuations in voltage by charging when the voltage rises and discharging when the voltage drops again. In some cases, voltage spikes are too fast for capacitors. These peaks are in the range of nanoseconds and microseconds, and they can easily reach twice or three times the normal battery voltage. Most consumers can tolerate these voltage peaks, even if they are much higher than the actual maximum rated voltage. If the voltage peak is too strong or recurs over a long period of time, the voltage regulator, capacitor and FET may be damaged and fail. The spike suppressor absorbs these voltage peaks and therefore cannot even reach harmful voltages.
