Inverter/Yoonseo Design
Overview
Youtube videos from Yoonseo on the waveforms in the Inverter.
Inverter 101, Part 1 Inverter 101, Part 2
Modules
Crowbar Circuit: Short Circuit Protection (I'd have that on the DC side, right after the battery)
Square Wave Generator
Triangle Wave Generator
Reference Sine Wave Generator
Sine Wave Amplifier
Feedback (reference voltage chip and comparator)
Notes on Inductive vs Resistive Loads
1) Inductive loads use magnetic fields. Examples - Motors, solenoids, and relays. If it moves, it's probably an inductive load.
2) Inductive loads can cause blowback voltage. Circuits should be protected from this by diodes.
3) Blowback is caused by a surge of voltage created by the collapsing magnetic field in an inductor.
3) Resistive loads convert current into other forms of energy, such as heat. No risk of blowback. [1]
