What are the parts of a capacitor diode?
A capacitor is basically composed of two conductive plates and a dielectric between the plates. Now these parts could also be represented in the varicap diode. The P-type and N-type regions of the diode are the conductive plates, and the depletion region is the dielectric.
Why are TVS diodes called clamp diodes?
TVS diodes (Transient voltage suppression diodes), also called clamp diodes, are electronic parts for protection, which can protect electrical equipment from voltage spikes introduced by wires. It is a high-performance circuit protection device commonly used internationally.
How is a TVS diode similar to a varistor?
The TVS (Transient Voltage Suppression) diode is a voltage limiting protection device whose function is very similar to that of the varistor. It also uses the non-linear characteristics of the device to clamp the overvoltage to a lower voltage value to protect the subsequent circuit.
What happens to the capacitance of the varicap diode?
When the reverse bias is decreased, the depletion region narrows, decreasing the separation between the P-type and N-type regions, thus increasing its capacitance. Therefore, varying the amount of the applied reverse bias on the varicap diode varies its capacitance.
When to choose continuous conduction mode when designing a boost converter?
When should we choose continuous conduction mode (or discontinuous) when designing a boost converter? DCM: more ripple current and inductor losses but easier to make stable. e.g. flyback but not scaleable > 200W , easy for no load. ( 1st order control system)
What is RMS current in DC boost converter?
A DC-DC boost converter, as shown in the figure below, is used to boost 360V to 400 V, at a power of 4 kW. All devices are ideal. Considering continuous inductor current, the rms current in the solid state switch (S), in ampere, is _________.
