A modelling and design approach for push/pull switched capacitor DC-DC converters …
This paper presents an extension to the switched capacitor DC-DC converter model when supplying loads stacked vertically. Stacking loads vertically drastically reduces the required size of a DC-DC converter, as it only needs to supply the mismatch current between the loads. Furthermore, when loads are perfectly matched, efficiency is only limited by the …

The results of a theoretical and experimental investigation of a capacitive-loaded push-pull parallel-resonant DC-DC converter (CL-PPRC) are presented and discussed. The converter is driven by a lower than resonance frequency, and the secondary voltage is rectified and smoothed by a capacitive filter. The CL-PPRC is shown to operate …

2 Tone Caps, 1 Push Pull Pot
Happy November! This month, we''re talking about a really cool simple Push-Pull Modification that allows you to choose between two cap values for your guitar. The 2 Tone Cap Push-Pull Pot Mod is great on a Strat or Telecaster, where you might have a Master Volume and a Blender Pot, but still want the capabilities of two Tone Caps.
Micro-power-consumption technique requires high power density DC/DC converters and power supply sources. The voltage lift technique is a popular method to apply in electronic circuit design. Since the switched-capacitor can be integrated into a power IC chip, its size is small. Combining both switched-capacitor and voltage lift techniques can construct the …

Push-Pull Class B and Class AB Amplifiers
We are now going to look at push-pull Class B and Class AB amplifiers, which are comprised of devices with conduction angles less than 360 degrees. These amplifiers can be made to be more efficient than Class A amplifiers, but suffer from a particularly undesirable form of distortion known as crossover distortion .
