Abstract:A pow er converting circuit of H -bridge bipolar P W M con trol is designed in order to decrease the pow er w astage. T he converting circu it decreases the pow er w astage, by w ay of reducing the sw itching tim e to 3.2 μs and selecting 600 H z as P W M sw itching frequency. H -bridge bipolar P W M control can be applied to high-pow er servo system to im prove the low velocity properties. T h e circuit has m any functions of protection, such as sh ort circuit protection and interlocked protection .
