Class 5 EMI Limits 23 Electric vehicle, solar power and industrial power applications place
significant power and efficiency demands on DC/DC converters.
In these environments, complex electronic controls and displays,
battery chargers, and high power electric motors operate from
wide-ranging battery voltages, various battery chemistries and
solar panels. DC/DC regulators must be able to both step-up, and
step-down their input voltages. Likewise, loosely regulated high
voltage industrial power systems require well regulated high voltage
and high current buck-boost bus …
