驱动感性负载的级联Buck-Boost功率放大器母线电压控制

Voltage of a bus capacitor in a cascaded buck-boost power amplifier is controlled to shape current in an inductive load. Switch-mode converter and inverter output higher power with higher efficiency than linear amplifiers. However, controlling current in the inductive load with low damping is not straightforward due to its inherent instability. Voltage-mode control of a front-end buck converter ad...
