This paper presents a nonlinear average current control method that regulates the true average of the inductor current by using the switch current as the feedback signal. The method is simple, requires no compensator design, and is very insensitive to switching noise. It combines the advantages of both peak current and linear average current control while overcoming their limitations. It can be used...
This paper presents a nonlinear average current control method which regulates the true average of the inductor current by using the switch current as the feedback signal. The method is simple and requires no compensator design. Unlike existing average current control where the control bandwidth is limited to about one tenth of the switching frequency, the proposed control method has no limitation...
A hybrid energy source has become a necessary solution for micro-scale applications, like wireless sensors, because of small form factor and extended lifetime requirements. Conventional power mixer circuits use two or more inductors, which become prohibitively area intensive in micro-scale applications where area for discrete inductors is scarce and on-chip inductors are poor. Although single inductor...
A ZVS three level two transistor forward DC/DC converter (input 600 V, output 48 V/50 A) is proposed. The performance of a 600 V/10 A silicon carbide (SiC) Schottky diode (Cree CDS10060) is experimentally evaluated on the prototype. Reverse recovery and overall efficiency are compared between the SiC diode and fast soft-recovery silicon power diode
