摘要： A control circuit is configured to sense an AC input voltage of a power factor correction (PFC) power circuit in a switching power converter, provide a control signal having an on-time and an off-time to at least one power switch of the PFC power circuit, and in response to detecting a peak voltage of the AC input voltage, increase the on-time of the control signal based on the sensed AC input voltage during an interval that begins with the peak voltage of the AC input voltage and ends with the next zero crossing following the peak voltage of the AC input voltage to improve a power factor of the switching power converter. Other example switching power converters, PFC power circuits and control circuits for controlling one or more power switches are also disclosed.

摘要： A method for controlling two electrically series-connected reverse-conductive (RC) IGBTs (RC-IBGT) of a half bridge is disclosed, wherein an operating DC voltage is applied across the series connection and one of the two series-connected reverse-conductive IGBTs operates in IGBT mode and another of the two series-connected reverse-conductive IGBTs operates in diode mode, and wherein each of the two reverse-conductive IGBTs has three switching states “+15V”, “0V”, “−15V”. The RC-IGBT T1 operated in diode mode does not go into the switching state (−15V) of highly charged carrier concentration, but instead into a state of medium charge carrier concentration associated with the switching state “0V”, and not into the switching state “−15V”, as is known from conventional methods. This reduces the reverse-recovery without adversely affecting the forward voltage.

摘要： Solid state switches of inverters are controlled by timing signals computed in power layer interface circuitry for individual inverters. Multiple inverters may be placed in parallel with common three-phase output. Common control circuitry generates timing signals or data used to reconstruct the common signals and sends these signals to the power layer interface circuitry. A processor in a power layer interface circuitry used these signals to recomputed the timing signals. Excellent synchronicity may be provided between parallel inverters that each separately reconstruct the timing signals based upon the identical received data.

摘要： A forward converter circuit includes a transformer having a primary winding and a secondary winding. A first transistor is coupled in series with the primary winding and a second transistor is coupled in series with the secondary winding. A control circuit generates PWM control signals for controlling operation of the first and second transistors. The control signals are generated responsive to source PWM signals processed through programmable delay timers to generate set/reset control signals which set an output PWM control signal duty cycle.

摘要： A signal control device controls the period of a three-phase signal used to control a three-phase high-voltage converter. An arithmetic unit of the signal control device determines a timing for changing the period for each phase so that the period of the signal for a V phase or a W phase is changed at the point when the phase difference between a U phase and the V or W phase reaches a prescribed phase difference after the period of the signal for the U phase has been changed. A control unit performs control such that the signal period for each phase is changed at the timing determined by the arithmetic unit.

摘要： Disclosed is a method of controlling an operation of a switching power converter which includes a first and second series connected transistors. Each of the transistors includes a conduction control terminal for receiving a conduction control signal. A first series of conduction control signals is applied to the control terminal of the first transistor and a second series of conduction control signals is applied to the control terminal of the second transistor, with the second series of conduction control signals being applied out of phase with respect to the first series of conduction control signals. A ratio of an input voltage to an output voltage for the series connected transistors is measured for a first spacing between an edge of a falling transition of the conduction control signal for the first transistor and an edge of a rising transition of the conduction control signal for the second transistor. The operation of the switching power converter is changed by providing a spacing having a second amount of time and the ratio of the input voltage to the output voltage for the second spacing is measured.
