[!TLDR]

Rectifier (AC→DC), AC voltage controller (AC→AC), DC chopper (DC→DC), Inverter (DC→AC).

Power converters are classified into four types according to the conversion performed:

Rectifier — converts AC to unipolar DC current (symbol: $\sim$ input to $-$ output).
AC voltage controller — converts fixed AC to variable AC of desired magnitude (symbol: $\sim$ to $\sim$ ).
DC chopper — converts constant DC to variable DC (symbol: $-$ to $-$ ).
Inverter — converts DC to AC of desired voltage and frequency (symbol: $-$ to $\sim$ ). …
