Two high-frequency inverters output simultaneously

Is dual frequency inverter a good choice for high power range?

Proposed dual frequency inverter offers good performance for medium and high power range. The proposed method is better in certain aspects in comparison with other multiple load configurations explained in introduction. The number of devices/loads is least in dual frequency inverter.

What is the efficiency of dual frequency inverter?

The number of devices/loads is least in dual frequency inverter. Since a dual frequency inverter is a combination of two half-bridge inverters, split capacitors of half-bridge configuration are avoided. Overall efficiency is comparable in medium and high power range with other configurations proposed in the literature.

Is dual frequency inverter better than other multiple load configurations?

The proposed method is better in certain aspects in comparison with other multiple load configurations explained in introduction. The number of devices/loads is least in dual frequency inverter. Since a dual frequency inverter is a combination of two half-bridge inverters, split capacitors of half-bridge configuration are avoided.

How many kHz is a dual frequency inverter?

The range of switching frequencies normally used with induction cooking is 20–150 kHz. In the prototype of dual frequency inverter, fh / fl is taken as five. For fl of 30 kHz, fh is taken as 150 kHz. In the prototype, both the induction heating coils are identical with equal inductances (Lr1 = Lr2).

Can dual frequency full-bridge inverter be used for two load induction cooking?

In this paper, dual frequency full-bridge inverter configuration for two load induction cooking application has been proposed. Both loads are independently controlled. It can be extended for more than two loads also.

What is a dual frequency full bridge resonant inverter?

Equivalent resistance and inductance of load-1 and load-2 are taken as the combination of induction heating coil and vessel. An induction heating coil is made with Litz wire. Table 1. Parameters of dual frequency full bridge resonant inverter A dual frequency full-bridge series resonant inverter is designed with the parameters shown in Table 1.
