Voltage drive system with hysteretic current control and method of operating the same |
摘要 |
A voltage drive system is provided having a plurality of modulators and a plurality of cascaded switching circuits which collectively generate a single-phase output signal to a load. Each modulator receives a phase current error and has an adder which generates a modulated phase current error based on the phase current error and based on a signal having a phase. For each respective modulator, the phase of the respective signal is different. Each respective modulator changes a respective gate input when the respective modulated phase current error changes from being within a predetermined current range to being outside of the predetermined current range. Each respective switching circuit receives the respective gate input and generates a respective output terminal voltage based on the respective gate input. The change in the respective gate input effectively causes a switching event of the respective switching circuit.
