Abstract
A boost conversion circuit includes a switch, a first diode, a first inductor, a first capacitor, a first energy storage module and a second energy storage module. When the switch is turned on, a voltage source charges the first inductor, the first capacitor, and the second energy storage module. When the switch is turned off, the second energy storage module charges the first energy storage module, and the load is simultaneously driven by the first capacitor and the first energy storage module. Via the above circuit operation mechanism, the first capacitor and the first energy storage module can drive a load requiring a high driving voltage, such that the load can achieve higher power.
