The NHW20 modelToyota PriusHEV uses a 500 V motor. Without a boost converter, the Prius would need nearly 417 cells to power the motor. However, a Prius actually uses only 168 cells and boosts the battery voltage from 202 V to 500 V. Boost converters also power devices at smaller scale...

The input voltage can be converted to a lower voltage level using a step-down mode, or converted to a higher level using a step-up mode. These 2 modes are supported with a single H-bridge converter using a non-inverting buck-boost topology. The STM32F334 microcontroller is...
A boost converter is one of the simplest types of switch mode converter. As the name suggests, it takes an input voltage and boosts or increases it. All it consists of is an inductor, a semiconductor switch, a diode and a capacitor.
It is composed of a current mode Boost converter integrated with a 36.5V/1.2A power switch. The RT4533/A supports a wide input voltage range from 2.5V to 5.5V and runs at a fixed frequency of 1.1MHz. The LED current is set via an external resistor and the feedback voltage is ...

In this project we build a simple boost converter circuit using a 555 timer IC. Boost converter is a non-isolated type of switch mode power supply that is used to step-up the voltage.
The MAX1605 boost converter contains a 0.5A internal switch in a tiny 6-pin SOT23 package. The IC operates from a +2.4V to +5.5V supply voltage, but can boost battery voltages as low as 0.8V up to 30V at the output. The MAX1605 uses a unique control scheme providing the highest eff...
• ΔVOUT is output voltage ripple. The output voltage drops when the inductor is storing energy, and increases when the inductor energy is released. This behavior results in output voltage ripple ΔVOUT defined by Equation 1. This formula is commonly found in boost converter data sheet. ...
The maximum peak inductor current occurs when the supply voltage is at the minimum value, VSUPPLY_min, and the maximum load current, ILOAD_max. The peak inductor current is calculated using Equation 4. This is the sum of the average input current and one-half the inductor ripple current. ...
