Single-Level and Two-Level Circuit Solutions for Buck-Boost AC Voltage Regulators with Phase-by-Phase Switches

Electricity
Forming required AC voltage levels is currently one of the most pressing problems. Unstable voltage levels can lead to the failure of household and industrial equipment. This can lead to a pure effect on the production cycle.
