  • Patent number: 10277146
    Abstract: Disclosed are half bridge inverter unit and inverter thereof. The half bridge inverter unit includes an inverter controlling module and inductors. The inverter controlling module provides different connection modes based on different operation modes so that the inverter meets the requirement of wide input voltage range as it can work in either voltage step-up mode or voltage step-down mode. The mid-point voltage between the DC series capacitors connected in parallel with DC power supply can be balanced automatically by taking advantage of the grid voltage symmetry with regard to positive and negative half cycles. The inverter is of single stage structure. It has advantages of low power loss, low cost, high efficiency and reliability.

  • Patent number: 10243473
    Abstract: An LED driver is provided having a gate drive integrated circuit with an adaptive operating mode which operates between a first operating mode and a second operating mode. The gate drive integrated circuit is designed to primarily operate in the first operating mode which includes a predetermined minimum on-time and a predetermined maximum off-time for enabling and disabling gate drive signals to a switch, respectively. The second operating mode begins at the minimum on-time and the maximum off-time. The LED driver further includes a controller configured to monitor an on-time and an off-time of the gate drive signals. The controller is further configured responsive to the second operating mode to fix the on-time equal to the predetermined minimum on-time and to continually adjust the off-time greater than or equal to the maximum off-time.

  • Patent number: 10236687
    Abstract: In a full-scale converter system both the grid-side inverter unit and the generator-side inverter unit have a series convection of parallel inverters and form a generator-side and grid-side voltage-center-point at a voltage level between those of the inverters connected in series. The voltage-center-points are electrically connected by a center-line conductor that has a cross-section between 30% and 70% of that of a positive or negative potential conductor. The converter system continues conversion operation in the event of a fault in an inverter of a first converter-string, with non-faulty inverters of the converter system, as the center-line conductor is dimensioned by said cross-section to carry a compensation current resulting from an unbalanced active power-output.

  • Patent number: 10224805
    Abstract: Methods and apparatus relate to a minimizing ripple in a polyphase power supply by modulating a voltage pre-regulator output setpoint to minimize ripple performance. In an illustrative example, the modulation may include incrementally adjusting the pre-regulator output setpoint supplied, for example, to a multiphase controller. Some examples may reverse the increment direction in response to determining that the prior incremental adjustment yielded increased ripple. Each phase of the polyphase power supply may include a buck-derived switch-mode power supply connected, for example, to a common output node. Various embodiments may advantageously maximize reduce bulk capacitance requirements for active loads by dynamically seeking a duty cycle of the polyphase power supply with substantially minimal ripple.

  • Patent number: 10218272
    Abstract: For controlling a switch power supply, an adjustment module produces a first control voltage by comparing a period of a switch signal with a reference period. A current source module generates a first charging current according to the first control voltage. A pulse signal generating module converts the first charging current into an on time signal or off time signal of a switch transistor. A driving module produces the switch signal according to the on time or off time signal of the switching transistor, so as to control the turn on and turn off signal of a switching transistor. A time measurement module obtains a time parameter according to the switch signal, and generates a periodic adjustment signal according to the time parameter. The adjustment module adjusts the reference period according to the periodic adjustment signal to adjust the period of the switch signal.
