Hi, Tony.

Perhaps the design approach should be to use a half-bridge inverter at 20 Hz driven with a switchmode PWM chip running at close to a 50% duty cycle.

Try getting in touch with several switchmode IC vendors. I'm sure their applications people will have seen this application before.

Good luck.
