Inverter circuit for minimizing switching power losses |
摘要 |
Because inverter circuits utilize switches which can be adversely affected by signal transients or excessive voltages, it is usual to provide a protective circuit consisting of a capacitor and a resistor. At high frequencies and high powers the energy dissipated in the resistor can be excessive. The present invention provides an additional switch, which is arranged to discharge the capacitor in a lossless manner and to return the energy stored by the capacitor to the power supply by making the discharge path part of a resonant circuit, loss can be reduced to negligible levels.
