Zusammenfassung: | The utility model belongs to the technical field of the power, in particular to indirect variable frequency power supply of SPWM based on DSP control. This indirectness variable frequency power supply includes rectification filtering circuit module, power factor correction circuit module, contravariant circuit module, filtering circuit module and DSP control?core circuit module. Relation of connection between each part does: DC power supply through a rectification filtering circuit module, is stabilized with converting to the input alternating current after the alternating?current?power?supply rectification, because rectification filtering circuit module reduces the harmonic through power factor correction circuit module and pollutes and carry high power factor the harmonic current serious pollution of electric wire netting, DC power supply passes through the inverter circuit module, converts the direct current to change according to the SPWM wave form alternating current under DSP control?core circuit module |
