Capacitive Voltage Divider as an AC Voltage Divider
Note that the ratios of the voltage drops across the two capacitors connected in a series capacitive voltage divider circuit will always remain the same regardless of the supply frequency. Then the two voltage drops of 6.9 volts and 3.1 volts above in our simple example will remain the same even if the supply frequency is increased from 80Hz to …

Novel PWM switched capacitor voltage dividers (SCVDs) are proposed for high step-down voltage conversion applications. The proposed PWM-SCVDs achieve greater stepdown voltage conversion at a given duty cycle than do conventional PWM buck converters, which suffer from extremely low duty cycle for high step-down applications. Fundamental …

If a circuit contains nothing but a voltage source in parallel with a group of capacitors, the voltage will be the same across all of the capacitors, just as it is in a resistive parallel circuit. If the circuit instead consists of multiple capacitors that are in series with a voltage source, as shown in Figure 8.2.11, the voltage will divide between them in inverse …

Get PriceMerged Switched-Capacitor Piezoelectric-Resonator Based DC-DC Converter with High Voltage Conversion Ratio
Piezoelectric devices have recently emerged as a promising candidate to replace magnetic components. Past research has explored different topologies and control strategies for dc-dc converters which only use a single piezoelectric resonator as the main energy-storage component. However, such converters exhibit relatively low efficiency when the voltage …
