Power Electronic Converters : PWM Strategies and Current Control Techniques

Power Electronic Converters : PWM Strategies and Current Control Techniques / edited by Eric Monmasson.

A voltage converter changes the voltage of an electrical power source and is usually combined with other components to create a power supply. This title is devoted to the control of static converters, which deals with pulse-width modulation (PWM) techniques, and also discusses methods for current co...
