摘要： A voltage step-up circuit, or booster circuit, wherein in response to a first signal a first switching element is enabled to charge a first capacitor with an input voltage while a second switching element is disabled, and in response to a second signal the second switching element is enabled to charge with the input voltage a second capacitor connected in series to the first capacitor while the first switching element is disabled. The sum of the voltages appearing across the first and second capacitors is derived as an output voltage. The "ON" and "OFF" times of the first and second signals may be varied, and the ratio between the "ON" time of the first signal to the "ON" time of the second signal may also be varied. The number of switching elements and capacitors may be increased as needed.

摘要： In described examples of methods and control circuitry to control a multi-level power conversion system, the control circuitry generates PWM signals having a duty cycle to control an output signal. The duty cycle is adjustable in different switching cycles. Each switching cycle includes a respective first sub-cycle with a first sub-cycle duration and a respective second sub-cycle with a second sub-cycle duration. The control circuitry controls a given switching cycle's first and second sub-cycle durations to control a voltage across a capacitor of the power conversion system while maintaining the given switching cycle's duty cycle.
