| May 11, 2022 at 19:11 | comment | added | Nick Lacarno | I'm not sure what you mean. The answer is no, obviously. The switching is PWM, sinusoidal PWM at 24 kHz. A choke on the transformer primary and filter capacitor on the secondary filter the PWM and the resultant sine wave is quite clean... Until I blow it up. | |
| May 11, 2022 at 19:02 | comment | added | Uwe | Do you really want a pure sine wave without any PWM switching? A pure analog solution with a lot of heat loss in the H bridge and a pour efficiency? | |
