Motor Control—Digital Bipolar Power Chopper
This note describes a way to directly produce house power without the need for a heavy, expensive, inefficient transformer. This application uses a large solar panel array and the PSoC 8-bit PWM with Deadband (PWMDB8) User Module to generate AC waveforms. Standard house 110V/60Hz AC has been selected as the target output. This is accomplished with two DC power supplies (batteries, bench supplies, solar cells, etc), a MOSFET half-bridge power section, and a PSoC. The signal is generated via a “breathing” pulse width output based on a hard-coded sine wave lookup table.
