Assertion: amplifier's circuit | /r/CapableOf | obtain high efficiency
Facets:
value: by operating the switching element
type: MANNER
Source sentences:
text: The circuit obtains high efficiency by only operating the switching element at points of zero current (on to off switching) or zero voltage (off to on switching) which minimizes power lost in the switch, even when the switching time of the devices is long compared to the frequency of operation.
