This is a blog that discusses some of the finer points of high-voltage switching power supply and DC/DC converters. The working principle behind a DC/DC converter is that the inductor (in the input resistance) has an unexpected variation in input current. If the switch is on, then the inductor feeds the energy from the input. It stores the energy as a result. If the switch is closed, it discharges the energy.
The output circuit is assumed to be a high-voltage switching power supply sufficient enough to work in the
system. There are two different types of working principles in the buck–boost
converter: Buck converter, Boost converter.
Fact: Each high-voltage low-current power supply is coupled with a DC/DC converter to
keep the bus voltage constant at 650 V. The parallel converter architecture
allows for greater flexibility in control (adding degrees of freedom).
Experts must take care to pay attention to the efficiency of
the operation, however. Power loss is a major concern here. For this reason,
the architecture has been provided with parallel battery packs to ensure the
proper energy supply under various circumstances. That’s why it is so important
to pick the right capacitor technology. The most vital relationship to consider
in choosing the capacitor is “cost” versus “size and impedance.”
In other words, the input and output capacitors must have
low impedance at a given switching frequency to limit voltage ripple and power
dissipation. For more details on the topic, please refer to www.hvmtech.com.
