The three basic switching power supply topologies in common use are the buck,
boost, and buck-boost. These topologies are non-isolated, i.e., the input and
output voltages share a common ground. There are however, isolated derivations
of these non-isolated topologies. The power supply topology refers to how the
switches, output inductor, and output capacitor are connected. Each topology
has unique properties, including the steady-state voltage conversion ratios, the
nature of the input and output currents, and the character of the output voltage
ripple. Another important property is the frequency response of the
duty-cycle-to-output-voltage transfer function.

老灭老了，没得几个记得你咯
你只有无奈地路过，回头绝望地希望有人回帖跟你打招呼来表示崇拜
