h-bridge

A schematic-only project to demonstrate how a bootstrap capacitor works. The overall circuit is a DC to DC Buck converter (see Buck converter, from Wikipedia):

• The control signal is a 20kHz, 50% PWM wave.
• The power source is 12V DC.
• The MOSFET is a N-Channel, requiring a positive voltage between gate and source of at least 5V.

To simulate it, use the following configuration:

• Transient
• Maximum timestep: 0.1us
• Stop time: 100us
• Start time: 0
