I am now designing a circuit for converting AC(220V) 50Hz to AC(220V)
60Hz or other frequency with the same voltage. The concept I am using
is just converting the AV into DC and convert it in different frequency
AC. The output for the circuit is only needed 1A to 2A maximum.
The circuit is shown as below and I found some problems on the circuit.
Once I connect the circuit with the AC motor, the circuit cannot be
afforded and burn out quickly. It is only in 0.5A consumption but still
burn out.
I really don't know the reason on it.
The schematic is shown as the following:

Perhaps:
(1) the motor can't handle a square waveform, or
(2) the driving circuit can't handle the lagging phase presented by the motor.
What frequency are you trying to drive the motor at?
What kind of motor are you using?
A motor designed for 60 Hz isn't likely to present adequate Xr to limit the
current through it when driven at a significantly lower frequency.
