Abstract: During a light load (or no-load) operation of a totem pole power factor correction circuit (i.e., PFC), a pulse width modulation (PWM) controller can operate in a skip mode. Further, the PWM controller may disable portions of the PFC to reduce standby power consumption. In this mode, and in this disabled configuration, the output of the PFC may be peak charged over time to a voltage that could be damaging or destructive. This peak charging results from the PFC circuit's inability to fully charge/discharge EMI capacitors between half cycles of the input line voltage. The present disclosure provides circuits and methods to fully charge/discharge the EMI capacitors to prevent peak charging the output.

Abstract: A handle attachment assembly that includes first and second insert members, and a handle assembly that includes a cover and a main body portion. The main body portion includes a handle portion and first and second attachment portions extending from the handle portion. The cover is removably connected to the main body portion and the main body portion and the cover cooperate to define a handle interior. The first and second attachment portions include first and second attachment members, respectively. The first attachment portion and the first insert member are secured together by a first fastener, and the second attachment portion and the second insert member are secured together by a second fastener.
