摘要： Switch controller circuit (10) for controlling switching in a topology (1) having a first switch (4), a second switch (5), and a switching node (6) coupled therebetween. A driver arrangement (101,104,105) controls the first and second switches (4,5) to alternately open and close, wherein a deadtime period is applied between the opening of one switch (4) and the closing of the other switch (5) in use. A voltage sensor (106) connected to the switching node (6) provides feedback based on a sensed voltage as it transitions between high and low voltage states and sets a length of the deadtime period based on a measured first time period and a multiplier coefficient. The first time period is measured from a time of opening of one of the switches to a time when the sensed voltage transitions through a threshold set between the high and low voltage states.

摘要： An energy recovery snubber circuit for a power converter which includes a flyback transformer driven by a converter switch is disclosed. The snubber circuit includes two capacitors which are connected such that, when the snubber circuit is connected to a primary winding of the flyback transformer, the capacitors are charged in series by current flowing in a first direction in the primary winding when the converted switch is turned OFF, to recover energy stored in the leakage inductance of the transformer, and discharged in parallel to cause current flow in a second direction in the primary winding of the transformer, to thereby transfer the recovered energy to the transformer.

摘要： Disclosed is a PFC (power factor correction) device for shaping an input current of a power converter. The device includes means for receiving a rectified input voltage derived from an AC input voltage; load determining means for determining a load value L which represents the power drawn by a load supplied by the power converter; current shaping means for shaping the input current of the power converter to follow a reference waveform; and control means for controlling the current shaping means to operate over a conduction interval α during each positive and negative half cycle of the AC input voltage. The duration of the conduction interval is controlled in accordance with the load value L. The current shaping means may shape the input current to follow the reference waveform which crosses zero at phase angles which substantially correspond to the start and end of the conduction interval.
