|
| For consumer electronics, Power Factor Converter(PFC) is required to improve input current power factor and to surpress harmonics. A single phase converter with 8-bit microcomputer brings high power factor. Because the controller is moduler, the whole unit can be easily customised by changing the power unit. We also developed three-phase converters with 16-bit microcomputer. |
