Figure 1. A complete 12 V isolated flyback converter for a wide input from 20 V to 800 V with a minimum start-up voltage of 260 V

­In traditional isolated high voltage flyback converters, tight regulation is achieved using optocouplers to transfer  regulation information from the secondary-side reference circuitry to the primary side. The problem is that optocouplers add significant complexity to isolated designs: there is propagation de

Figure 1: Ac charging diagram

­EVs can now achieve similar mileage as gas-powered vehicles, but it still takes more time to charge an EV than to refuel a gas vehicle. Charge time is approximately equal to the amount of energy delivered to the battery divided by the charging power; therefore, it is desirable to use as much power as possible to

Figures 1a: Filtering normal-mode

­EMI-RFI filters are needed to attenuate common-mode and differential-mode EMI (or noise). Although simple in principle, they are not easy to design and often require specialist help. Moreover, in three-phase power applications, adequate filtering can occupy a large volume. An integrated three-phase filter ca
