 移動電源的DC- DC轉換器，完全隔離電池充電器負尖峰
The operation of a motor control device, commonly
used on forklifts, front end loaders, small utility vehicles utilizing
thyristors, can cause a negative spike to be generated. Any electronics
sharing a common power system can be affected by these negative spikes.
Analytic Systems has developed a modification to prevent these negative
spikes from accidentally shutting down power conversion units. We are
often called upon to supply fully isolated DC-DC converters to produce
15 - 16 volts DC, at 5 to 7 amps from forklifts, 36 or 48 volts DC to
run notebook computers.

Raymond, BC Hydro, Oshkosh, NBC, Duke Energy.
The ‘Forklift’ Modification
These are particularly tough applications, as the thyristor-based motor
drives for the forks and tires produce large amounts of overlying AC on
the batteries, and will cause many converters to fail unless proper
input-circuitry is used. We call this the ‘Forklift’ Modification.
