Problem Two $(12pts,1\mathrm{.}5pts$ each part$)$

Select True or False:

Compared to thyristors, MOSFETs have a much higher speed

True I False

An inverter is a power electronics circuit that converts an $AC$ input voltage to a DC output voltage.

True I False

In order to produce a sinusoidal waveform from a square waveform, an inverter must use a low$-$pass filter.

True I False

The main advantage of full$-$bridge inverters compared to half$-$bridge is they have reduced filtering requirements.

True I False

Controlled rectifiers are controlled by controlling their switching frequency.

True I False

Fourth order DC$-$DC converters have less efficiency than second order DC$-$D converters.

True I False

A charger supplies $50$ W to a $100$ Wh battery. The total charging time assumir completely discharged battery is $120$ minutes.

True $|$ False

Controlled Rectifiers operating in inversion mode have a firing angle betwe and $90.$

True I False
